fcond=gabrieszbounds(g,a,M); [A,B]=gabrieszbounds(g,a,M); [A,B]=gabrieszbounds(g,a,M,L);
| g | The window function. |
| a | Length of time shift. |
| M | Number of channels. |
| L | Length of transform to consider. |
| fcond | Frame condition number (B/A) |
| A, B | Frame bounds. |
gabrieszbounds(g,a,M) calculates the ratio \(B/A\) of the Riesz bounds of the Gabor system with window g, and parameters a, M.
[A,B]=gabrieszbounds(g,a,M) calculates the Riesz bounds A and B instead of just the ratio.
The window g may be a vector of numerical values, a text string or a cell array. See the help of gabwin for more details.
If the optional parameter L is specified, the window is cut or zero-extended to length L.
