The signal package is part of the Octave Forge project and provides signal processing algorithms for use with Octave. The functions provided by the signal package include creation of waveforms, FIR and IIR filter design, spectral analysis, Fourier and other transforms, window functions, and resampling and rate changing. There are also some wavelet functions included, because there is no separate wavelet package, at least for now.
You may also be interested in the LTFAT package.
Missing Functions
This is a list of functions that are not yet implemented in the Octave signal package. Patches for some of these functions are available on the patch tracker and are undergoing review. You could help us by implementing the missing functions and adding them to the patch tracker, or by helping us review the ones that are already there. This list is subject to change and may not be complete in any sense. However, it is a starting point when looking for missing functionality or for possible projects to work on.
