Zeros
Leading::Zeros is a Perl module to defuse Perls octal number representation. SYNOPSIS no Leading::Zeros; my $answer = 042; # dies This module offers some control over Perls insidious "leading-zero-means-octal" notation. INTERFACE If the module is loaded via a no: no Leading::Zeros;...

The INTERPFT function does sinc interpolation by taking an FFT, padding its end with zeros, and then taking an IFFT. Essentially, INTERPFT resamples the signal after low-pass filtering it.Instead of putting all zero padding at the FFT *ends*, that padding can be split so that some are at the...

RGrow resizes fixed length records e.g. RGrow.exe MyFile.seq 500 600 will grow each record from 500 to 600 bytes by padding binary zeros. Will also truncate records. These are not the old and new sizes of the file, but of the fixed length records in the file. If you increase the record size, each...

A function that takes two sequences(vectors) as parameters and computes the circular convolution .x(n),h(n) are the vectors.The vectors need NOT be of equal lengths.If they are of unequal lengths, the shorter vector is appended with trailing zeros and then circular convolution is carried out.
