*MathemaTcl* is a collection of compiled extensions for Tcl, each intended to solve a particular numerical problem. Currently the following extensions are available:

- CEPHES - a library for evaluating special mathematical function, such as the various Bessel functions and exponential integral functions.

- FFTPACK - a one-dimensional FFT package (derived from the SLATEC library)

- GLOBAL - a package to find the global minimum of a function of one or several variables

- MILLER - a variety of numerical algorithms, such finding zeroes of functions

- ORDERPACK - a library for a variety of ordering and ranking algorithms

- QUADPACK - a package for the automatic integration of functions over finite or infinite intervals

- SPECFUNC - a collection of routines to evaluate special mathematical functions, such as Bessel functions of the first and second kind, exponential integrals and the like.

- WAVELIB - a library for wavelet transforms

- There are several Packages in preparation

**Warning:** This is work in progress at the moment. For most packages documentation is now available, but they should be tested more extensively.

There are a number of other issues that need to be taken care of.
