[AF,BF]=wilbounds(g,M) [AF,BF]=wilbounds(g,M,L)
| g | Window function. |
| M | Number of channels. |
| L | Length of transform to do (optional) |
| AF, BF | Frame bounds. |
wilbounds(g,M) calculates the frame bounds of the Wilson frame operator of the Wilson basis with window g and M channels.
[A,B]=wilbounds(g,a,M) returns the frame 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 wilwin for more details.
If the length of g is equal to \(2\cdot M\) then the input window is assumed to be a FIR window. Otherwise the smallest possible transform length is chosen as the window length.
If the optional parameter L is specified, the window is cut or zero-extended to length L.
