h=iframemul(f,Fa,Fs,s); [h,relres,iter]=iframemul(...);
| Fa | Analysis frame |
| Fs | Synthesis frame |
| s | Symbol |
| f | Input signal |
| 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. |
