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.
