INSDGTREAL Inverse NSDGT for real-valued signals
Usage: f=insdgt(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 : Vector of numbers of frequency channels.
Ls : Length of input signal.
Output parameters:
f : Signal.
insdgt(c,g,a,Ls) computes the inverse non-stationary Gabor transform
of the input coefficients c.
insdgt is used to invert the functions NSDGT and UNSDGT. Please
read the help of these functions 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
using NSGABDUAL or NSGABTIGHT.
