This Toolbox was ported from the Time-Frequency Toolbox http://tftb.nongnu.org/.
The toolbox contains numerous algorithms which implements various kind of
time-frequency analysis with a special emphasis on quadratic energy
distributions of the Cohen and affine classes, along with their version enhanced
by the reassignment method. The toolbox also includes signal generation
procedures, processing/post-processing routines (with display utilities) and a
number of demonstrations.
