Thread Subject: 2007a and Mac 10.5 Leopard

I searched the newsgroup and google for any information on the
compatibility of MatLab 2007a and the upcoming MacOSX 10.5 (Leopard).


Has anyone run 2007a on a developer build of 10.5? My office is
looking to upgrade hardware (intel macs) and this compatibility is a
factor in the purchasing schedule (buy now or buy after 10.5 comes
out).

Thanks!

Hi Jeff,

R2007a already runs natively on all Intel Macs with Mac OS X 10.4, so
why is this decision based on whether MATLAB works on Leopard?

The MathWorks works closely with Apple to ensure that our current
releases work with significant future Mac OS updates, such as Leopard.

However, Leopard pre-release "seeds" require non-disclosure agreements,
so an individual could be violating their NDA if they share information
regarding pre-release seeds.

If you'd like to know whether we test or "pre-qualify" our products on
Apple seeds internally, we have a process for doing this, but it is not
the same as formal qualification, which requires the final Leopard release.

So, the best guidance I can offer is, things are looking good with the
current Leopard seed. However, if you read the Mac rumor web sites,
many of these web sites are indicating that Apple isn't finished yet
with Leopard development and has more surprises for developers and
users; if they're right, our situation with regard to compatibility
could change, and any information you might get now would become invalid
by the time it ships.

So, your best bet is to not condition MATLAB or Intel Mac purchases on
Leopard, or information regarding MATLAB compatibility, until after
Leopard has shipped.

Any updates on how Matlab behaves with the final Leopard seeds?

I'm hoping to be able to upgrade next week and keep on truckin'.

Hi Jerrod,

There should be official information on www.mathworks.com regarding
compatibility and any known issues once Leopard is available, or shortly
thereafter.

FWIW,

I am having problems with the installer from 2007b and Leopard. The
shortcuts are created on the desktop, but there is no executable in bin
folder...

Any advice?

Thanks,

Hi John,

Do you have a PowerPC or Intel-based Mac? Is there a mac or maci folder
in the bin folder? What happens when you click the shortcut? You might
be better off contacting support.

This particular machine is a PowerPC based machine that I am using as a test
machine for compatibility before upgrading other machines to Leopard.

I downloaded the MATLAB installer directly from the website.

There is no mac or maci folder in the bin folder - looks like the installer isn't
creating it.

Is Leopard officially supported, or are they going to laugh at me if I call tech
support? :)

I realize that a pre-installed version of MATLAB on an upgraded machine
might still work - I was specifically testing the installer.

Thanks for any advice,

JAW

Leopard is supported, see:

< http://www.mathworks.com/support/sysreq/current_release/macintosh.html >

I think your issue may be with the installer not installing, I don't
think it's related to Leopard. I would check your download
(re-downloading "Mac (PowerPC)") and your license file.

OK Brian - thanks for the link! Nice to see support so quickly after release.
We in the Mac community appreciate it. I will probably not troubleshoot the
installer issue unless I see it on multiple machines - I will try from the disks
at some point too.

Thanks again,

Hi Brian.

I upgraded my iMac (intel, 2.8 GHz, 4GB RAM) from Tiger to
Leopard and the Matlab interface (Matlab ver. 2007b) got
much slower. In particular when scrolling in Editor the
response was so slow that I really couldn't work.
Reinstalling X11 and Matlab didn't improve things.

Am I missing something there? Is there something I
should/shouldn't have done?

Thanks in advance,
Viton

I see the same behaviour on a PPC Dual G5 (with 2 Gb memory). It ain't so
slow that I can't work, but it's slow enough to be majorly annoying, to the
point that you start issuing commands multiple times since the system
appears unresponsive...

Bench numbers do not seem different from what they were, so my initial
guess would be that it has something to do with the java interface. Hope it
gets sorted out though...

Hi,

Does turning off the MATLAB Preferences -> Editor -> Code Folding
"Function Code" result in better scrolling performance?

We will investigate this further.

Hi,

This appears to be a performance regression in Java when using the Sun
renderer, which Java on Leopard defaults to using, but Java on Tiger
does not.

If you create a file named java.opts in /Applications/MATLAB_R2007b and
add the following:

  -Dapple.awt.graphics.UseQuartz=true

then you should be able to get back to Tiger's performance. We will
work with Apple on a more permanent solution.

Hi Brian,

thanks for the quick response. Your reputation guys is well deserved :)

The second suggestion (i.e. use the quartz renderer) is indeed the solution,
even with code folding enabled!

(Disabling the code folding alone indeed speeded up scrolling, but not quite
to the desired point.)

Thanks again,
Viton

dear brian,

i have done this and it works fine since then. however, another minor problem
occurs here with leopard on a mac pro and the newest R2007b. i am using
matlab in spaces in a separate window. after hiding (apple-H) or minimizing
(apple-M) matlab and bringing it back, some keys do not work, in particular i
can't use the return key and backspace for deleting, both in the editor and
command window, whereas typing new characters work fine. so i have to quit
matlab using the menu - typing quit in the command window works, but the
return key does not work. now i simply avoid hiding matlab.

all the best, martin

PS thanks for helping us in this newsgroup

I can replicate this behavior.

However, simply switching focus away from the editor
(whether to another app or, if the editor is undocked, to
the another MATLAB window) restores expected behavior.

An added bit of info: It seems like the command button
doesn't work when the bug surfaces as well.

and really, while we're on bug reports..

i'd love to be able to use cntrl-a and cntrl-e to go to the start and
end of a line, respectively =). i could have sworn i've been able to
in the past.

AND...MATLAB will randomly move all of its windows to the
primary space when using spaces.

Haven't been able to reliably recreate this problem but I do
know that the editor is in a separate window, the command,
current dir, and history are in one pane in the main window,
along with the workspace in the other pane, and there are
two figure windows open.

the obvious workaround is rearranging spaces so matlab takes
the primary space and everything else moves...

adding the java.opts file did not speed up my scrolling...is something
else the cause? i disabled code folding also...

any ideas?

actually, after i did that, if i copy a page worth of code into the
command window...it now takes a little while to paste just that small
amount....i took the java.opts file out of the directory, restarted
the computer and all, and its still slow now.....are there any files i
can rebuild or anything of the sort? im thinking of reversing to 2007a
or tiger....but 2007b w/ leopard is making matlab not work very
smoothly....quite unfortunate.

make sure your java.opts file is actually a .opts file - use
"get info" in finder to double check the extension, and then
ensure you put it in the right place. the fix seems to have
worked for everyone else here.

hey...i checked that. here's the update:

it seems that something else is a little quirky on here. it was indeed
a .opts file, no .opts.rtf ...i double checked that. it was running
slow, so i tried deleting the file, rewriting it, so on. that did
nothing, so i rewrote setting it =false. restarted matlab with this,
closed it, rewrote the file with =true. after 2 restarts, it worked.
now it is running fine, i'm not sure if it was rebuilding something or
what, but it seems to be working fine now. i guess it just took matlab
a little while to understand that i reallyb needed it to work. stuff
copies fine now and scrolls great. i feel like matlab is back on my
side! thanks for the help tho.

 When I put the java.opts file in the matlab root directory, it doesn't boot. The
X11 app launches, then the MATLAB.app launches but no window comes up.

Hi,

Is there any message in Console (Applications -> Utilities ->
Console.app)? Is a crash log being created in your home folder
(matlab_crash_dump.nnnn)?

What happens when you start in xterm from the command line:

  cd /Applications/MATLABR_2007b/
  ./bin/matlab

I figured out that it's starting up in the X11 window. I'm using the 2007a
student version, so the command prompt EDU>> appears after starting up
bin/matlab from an X11 terminal however the terminal doesn't accept
commands. It appears that the matlab desktop does not startup since java is
disabled?? Out of curiosity, I took the java.opts file out of the root directory,
and I created a startup.m file, and disabled the matlab desktop with the
following command: matlab -nojva. This produced the same result as the
java.opts file. Perhaps quartz cannot run the desktop???

Hi Matthew,

Can you provide the exact xterm output when you launch in xterm? Also,
is there output in the Console application when you launch?

If the presence of this file is causing the UI to not show up at all, it
is possible that the format or content of the file is the cause. Check
that the file type is really unformatted ascii text (not RTF format, for
example, as TextEdit would save as), and contains the expected text
spelled and capitalized exactly as follows:

-Dapple.awt.graphics.UseQuartz=true

Use emacs from the command line, Xcode's text editor or some other real
text editor (not TextEdit) to ensure that the file is unformatted ascii
text, and confirm the file's contents.

Dear Brian

I'm running R2007b w Leopard on a MacBook Pro w 4 GB RAM. When I switch
to another application from MATLAB and then switch back to MATLAB (either
using the Dock or Command-Tab), although the MATLAB window is now
foremost, it only becomes active when I click in it. This is a very minor bug,
but I wondered if there was a fix.

Many Thanks

Andrew

Hi Andrew,

This appears to be a new issue, and I am able to reproduce it on 10.5.1
using both R2007a and R2007b. Are you using 10.5.1 by chance?

I haven't yet had time to track down this issue, and I don't yet have a
workaround.

Dear Brian

Yes, I'm using 10.5.1 and thanks for the speedy reply. No rush on
workaround, my fingers still work!

Worked for me!

Hi.

I have a new Intel-based iMac 2.8GHz with 10.5.2 and (in
both bench.m and my code previously written on XP) seems
much slower than the same or less frequency (also Core 2
Duo) CPU running XP. I am not referring to the well known
GUI issue, but the actual mathematical operations. This is
extremely frustrating and I think it may be be an issue for
all Mac users. I have seen some info in the web, but without
actual answers. Any ideas? What about the the Lapack and
other libraries binaries the right ones for the new
Intel-based Macs? Any reply from any Mathworks people would
be great ...

Many thanks in advance,

Yannis

All,

I am running 2008a on 10.5.2. I had the same poor java
performance, and tried the java.opts solution. When
launching matlab from the startup script provided by the
installation, either from finder or from the dock, there was
no change. However, starting matlab from a terminal using
./bin/matlab did solve the problem.

This seems a pretty serious bug. While I'm griping, I am
constantly annoyed that matlab occupies two spots on my dock
when running (three when you count X11). The first is a
shortcut, the second is the actual process. Is there no way
around this?

Ray

Hi,

Please type this at the MATLAB command prompt:

java.lang.System.getProperty('apple.awt.graphics.UseQuartz')

If that returns false, then your java.opts file isn't getting read.

For R2008a, please locate java.opts inside the bin/maci folder.

As for solving the "how many friggin' application dock icons does this
application need?" problem, we realize this is frustrating but were
unable to resolve it in time for R2008a. We're working on that, and
reducing or eliminating the X11 dependency, without losing some of the
modes customers love (see other threads on this newsgroup for customer
pros and cons).

- Brian

The java.opts fix worked for the scrolling issue, but now I
get some Java error messages in my command window when
Matlab launches:

They appear to be inconsequential, because Matlab seems to
