To use the toolbox, 'cd' to the LTFAT directory and execute 'ltfatstart'.

In Octave you can put this command in your ~/.octaverc file.

Directory struture.

The toolbox is organized in subdirectories including the following:

fourier - Fourier analysis, DCT/DST transforms and filtering.

gabor - Gabor, Wilson and WMDCT analysis/synthesis functions.

wavelets - Wavelet analysis/synthesis, wavelet filter banks

filterbank - General and auditory inspired filterbanks.

nonstatgab - Non-stationary Gabor frames.

quadratic - Quadratic distributions

frames - Frame objects and linear operators associated with frames.

sigproc - A collection of simple, signal processing tools.

blockproc - Methods for block processing and block-adapted transforms.

auditory - Auditory scales and common filters types.

demos - Demos showing applications or aspects of LTFAT functions.

signals - Test signals for use with the examples.

comp - Computational subroutines.

These should not be called directly.

src - C implementation of the most computationally intensive

routines.

mex - Mex files to speed up the toolbox (if compiled)

oct - Octave C++-files to speed up the toolbox (if compiled)

The file INSTALL contains instructions for compiling the C-library and

the Octave and Matlab interfaces.
