Lc=wfbtclength(Ls,wt); [Lc,L]=wfbtclength(...);
Lc=wfbtclength(Ls,wt) returns the lengths of coefficient subbands obtained from wfbt for a signal of length Ls. Please see the help on wfbt for an explanation of the parameters wt.
[Lc,L]=wfbtclength(...) additionally returns the next legal length of the input signal for the given extension type.
The function support the same boundary-handling flags as the fwt does.
