IFRAMEMUL Inverse of frame multiplier
Usage: h=iframemul(f,Fa,Fs,s);
[h,relres,iter]=iframemul(...);
Input parameters:
Fa : Analysis frame
Fs : Synthesis frame
s : Symbol
f : Input signal
Output parameters:
h : Output signal
IFRAMEMUL(f,F,s) applies the inverse of the frame multiplier with
symbol s to the signal f. The frame Fa is used for analysis
and the frame Fs for synthesis.
Because the inverse of a frame multiplier is not necessarily again a
frame multiplier for the same frames, the problem is solved using an
iterative algorithm.
[h,relres,iter]=IFRAMEMUL(...) additionally returns the relative
residuals in a vector relres and the number of iteration steps iter.
IFRAMEMUL takes the following parameters at the end of the line of
input arguments:
'tol',t Stop if relative residual error is less than the
specified tolerance. Default is 1e-9
'maxit',n Do at most n iterations.
'print' Display the progress.
'quiet' Don't print anything, this is the default.
