Computes the inverse discrete wavelet transform x for
input signal y using the scaling filter h.
Usage
midwt(y, h, L)
Arguments
y
Finite 1D or 2D signal (implicitly periodized)
h
Scaling filter to be applied
L
Number of levels in wavelet decomposition.
In the case of a 1D signal, length(x) must be divisible by $2^L$;
in the case of a 2D signal, the row and the column dimension must be
divisible by $2^L$. If no argument is specified, a full DWT is returned
for maximal possible L.
