These routines implement fast Hadamard and Walsh Transforms
and their inverse transforms.
Also included are routines
for converting a Hadamard to a Walsh transform and vice versa,
for calculating the Logical Convolution of two lists,
or the Logical Autocorrelation of a list,
and for calculating the Walsh Power Spectrum -
in short, almost everything you ever wanted to do with a Walsh Transform.
Intelligible speech can be reconstructed by transforming
blocks of, say, 64 samples, deleting all but the several largest
transform components, and inverse-transforming;
in other words, these transforms extract from a time-series
the most significant things that are going on.
They should be useful for noticing important things,
for example in software that monitors time-series data such as
system or network administration data, share-price, currency,
ecological, opinion poll, process management data, and so on.
As from version 1.10, Math::WalshTransform uses C routines to perform
the transforms. This runs 25 to 30 times faster than previous versions.
Not yet included are multi-dimensional Hadamard and Walsh Transforms,
conversion between Logical and Arithmetic Autocorrelation Functions,
or conversion between the Walsh Power Spectrum and the Fourier Power Spectrum.
