Math::FFT - Perl module to calculate Fast Fourier Transforms

This module implements some algorithms for calculating Fast Fourier Transforms for one-dimensional data sets of size 2^n. The data, assumed to arise from a constant sampling rate, is represented by an array reference $data (as described in the method...

PDL::PP - Generate PDL routines from concise descriptions

Now that you have some idea how to use "pp_def" to define new PDL functions it is time to explain the general syntax of "pp_def". "pp_def" takes as arguments first the name of the function you are defining and then a hash list that can contain variou...

Acme::AlgebraicToRPN - convert algebraic notation to sane RPN

Given a string with algebraic notation, convert to RPN, which is what any crappy dime store calculator needs to do anyway. Doesn't really process anything, that's up to you. You will get an array back with all of the variables and operations in RPN f...

Math::PhaseOnlyCorrelation - calculate the phase only correlation

This module calculate Phase Only Correlation coefficients. This measures degree of similarity between two waves (signals) heed to only phase component, so this method is not affected by an amplitude difference. The more similar two signals (waves), c...
