Random Numbers in Matlab, C and Java   
None of these languages provide facilities for choosing truly random numbers. They just provide pseudo-random numbers. But, we'll pretend that they are random for now, and address the details later.

Sorting and Searching Strings   
We present theoretical algorithms for sorting and searching multidimensional data and practical C implementations for the application where keys are character strings. The sorting algorithm, an amalgam of Quicksort and radix sort, is competitive with the best known C sort codes. The searching algorithm, an amalgam of trees and binary search trees, is faster than hashing and other commonly used search methods. The basic ideas behind the algorithms date back at least to the 1960s, but their practical utility has been overlooked. Analytic results and extensions to more difficult string processing problems are also included.

UNIFORM - A Uniform Random Number Generator   
UNIFORM contains some MATLAB routines to compute uniformlyl distributed pseudorandom numbers. MATLAB already has the random function, and it is not the purpose of uniform to replace it. Rather, this routine makes it possible to compare certain computations that use uniform random numbers, written in C++, FORTRAN90 or MATLAB.

JQuantity   
JQuantity is a framework of classes for developing mathematical and scientific calculations which are either precise or have known (bounded) precision. The classes in the framework are based on the java.math.BigInteger class and thus are not limited in size or precision. Rational numbers are stored as ratios, transcendental numbers are represented in their own domain, typically precisely.

chebfun - Chebyshev Function System   
The chebfun project is a collection of algorithms, and a software system in object-oriented MATLAB, which extends familiar powerful methods of numerical computation involving numbers to continuous or piecewise-continuous functions. It also implements continuous analogues of linear algebra notions like the QR decomposition and the SVD. The mathematical basis of the system combines tools of Chebyshev expansions, fast Fourier transform, barycentric interpolation, Clenshaw-Curtis quadrature, and recursive zerofinding. A chebfun is a function of one variable defined on an interval [a,b]. The syntax for chebfuns is almost entirely the same as the usual MATLAB syntax for vectors, with the familiar MATLAB commands for vectors overloaded in natural ways. The aim of the chebfun system is to "feel symbolic but run at the speed of numerics". More precisely the vision is to achieve for functions what floating-point arithmetic achieves for numbers: rapid computation in which each successive operation is carried out exactly apart from a rounding error that is very small in relative terms. The chebfun system was originally created by Zachary Battles and Nick Trefethen at Oxford during 2002-2005. Battles left the project in 2005, and meanwhile three new members have been added to the team: Ricardo Pachon (from 2006), Rodrigo Platte (from 2007), and Toby Driscoll (from 2008).
