IUNSDGTREAL Inverse uniform non-stationary discrete Gabor transform
Usage: f=iunsdgtreal(c,g,a,M,Ls);
Input parameters:
c : Cell array of coefficients.
g : Cell array of window functions.
a : Vector of time positions of windows.
M : Numbers of frequency channels.
Ls : Length of input signal.
Output parameters:
f : Signal.
IUNSDGTREAL(c,g,a,M,Ls) computes the inverse uniform non-stationary Gabor
expansion of the input coefficients c.
IUNSDGTREAL is used to invert the function UNSDGTREAL. Read the help of
UNSDGTREAL 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.
