GABMUL Apply Gabor multiplier
Usage: h=gabmul(f,c,a);
h=gabmul(f,c,g,a);
h=gabmul(f,c,ga,gs,a);
Input parameters:
f : Input signal
c : symbol of Gabor multiplier
g : analysis/synthesis window
ga : analysis window
gs : synthesis window
a : Length of time shift.
Output parameters:
h : Output signal
GABMUL has been deprecated. Please use construct a frame multiplier
and use FRAMEMUL instead.
A call to GABMUL(f,c,ga,gs,a) can be replaced by :
[Fa,Fs]=framepair('dgt',ga,gs,a,M);
fout=framemul(f,Fa,Fs,s);
Original help:
--------------
GABMUL(f,c,g,a) filters f by a Gabor multiplier determined by
the symbol c over the rectangular time-frequency lattice determined by
a and M, where M is deduced from the size of c. The rows of c*
correspond to frequency, the columns to temporal sampling points. The
window g will be used for both analysis and synthesis.
GABMUL(f,c,a) does the same using an optimally concentrated, tight
Gaussian as window function.
GABMUL(f,c,ga,gs,a) does the same using the window ga for analysis
and gs for synthesis.
The adjoint operator of GABMUL(f,c,ga,gs,a) is given by
GABMUL(f,conj(c),gs,ga,a).
