The WavBox® Software Library is the original Wavelet
Toolbox for MATLAB, the first available as free software in 1991, and the first
available as commercial software in 1994.
The FirWav® Filter Library contains algorithms
for numerically computing filter coefficients for the complete set of both complex
and real min-length max-flatness Daubechies wavelet filters. It also contains a
comprehensive set of routines for the analysis and display of these filters.
The original Daubechies wavelet families have been extended and systematized to
include many new families such as the family displayed below. All of these filter
families permit perfect reconstruction from a signal decomposition computed with
a wavelet transform 2-band filter bank in which the scalet is the lowpass filter
and the wavelet is the highpass filter. More examples of the various families can
be found on the FirWav Page.

As a MATLAB Connections Partner, Toolsmiths develops software libraries and provides
consulting services for the MATLAB technical computing environment available from
The MathWorks Inc. The
WavBox and FirWav Libraries are compatible with
both recent 7.* as well as older 5.* and 6.* versions of MATLAB.
