IFWT2 Inverse Fast Wavelet Transform
Usage: f = ifwt2(c,w,J)
f = ifwt2(c,w,J,Ls,...)
Input parameters:
c : Coefficients stored in a matrix.
w : Wavelet filters definition.
J : Number of filterbank iterations.
Ls : Size of the reconstructed signal.
Output parameters:
f : Reconstructed data.
f = IFWT2(c,w,J) reconstructs signal f from the wavelet coefficients
c using a J*-iteration synthesis filterbank build from the basic
synthesis filterbank defined by w. f is a matrix with
size(f)==size(c).
f = IFWT2(c,w,J,Ls) works as above but the result f is cut or
extended to size Ls if Ls is a two-element vector or to [Ls,Ls]
if Ls is a scalar.
This function takes the same optional parameters as FWT2. Please see
the help on FWT2 for a description of the parameters.
