-----BEGIN PGP SIGNED MESSAGE-----

Announcing the release of the following Perl Math Modules which I have
uploaded to CPAN under my home directory.

Math::Amoeba - Multidimensional Function Minimisation
	       using the Downhill Simpex Method

This is an implimenation of the Downhill Simpex Method in
Multidimensions (Nelder and Mead) for finding the (local) minimum of a
function. Using Perl makes it easy for that function to
be the output of another program such as a simulator.
Filename: Math-Amoeba-0.01.tar.gz

Math::Brent - One-Dimensional Function Minimisation
	       using Brent's method

This is an implementation of Brents method for One-Dimensional
minimisation of a function without using derivatives. Using Perl makes
it easy for that function to be the output of another program such as
a simulator.
This module requires Math::VecStat and Math::Fortran.
Filename: Math-Brent-0.01.tar.gz

Math::Derivative - Numeric 1st and 2nd order differentiation of data

This Perl package exports functions for performing numerical first
 and second order differentiation on data. They functions take
references to two arrays containing the x and y ordinates of the data
and return an array of the 1st or 2nd derivative at the given x
ordinates. The 2nd derivative may optionally be given values to use
for the first dervivative at the start and end points of the data -
otherwise 'natural' values are used.
Filename: Math-Brent-0.01.tar.gz

Math::Fortran - Perl implimentations of Fortrans sign and log10 functions

Filename: Math-Fortran-0.01.tar.gz

Math::Spline  - Cubic Spline Interpolation of data

This package provides cubic spline interpolation of numeric data. The
data is passed as references to two arrays containing the x and y
ordinates. It may be used as an exporter of the the numerical
functions or, more easily as a class module.
Filename: Math-Spline-0.01.tar.gz

Math::VecStat - Some basic numeric stats on vectors

   This package procides some basic statistics on numerical
vectors. Included are max , min , sum , average.
Filename: Math-VecStat-0.01.tar.gz
