IUNSDGT Inverse uniform non-stationary discrete Gabor transform
Usage: f=iunsdgt(c,g,a,Ls);
Input parameters:
c : Cell array of coefficients.
g : Cell array of window functions.
a : Vector of time positions of windows.
Ls : Length of input signal.
Output parameters:
f : Signal.
IUNSDGT(c,g,a,Ls) computes the non-stationary Gabor expansion of the
input coefficients c.
IUNSDGT is used to invert the function NSDGT. Read the help of NSDGT
for details of variables format and usage.
For perfect reconstruction, the windows used must be dual windows of
the ones used to generate the coefficients. The windows can be
generated unsing NSGABDUAL.
