 Usage:  x = invfwt2 (c, l, h, a)  

 

 Input:



  c                      n x n matrix, wavelet coefficients, retrieved e.g. by fwt2. 

                         n has to be a power of 2 

                         

  l                      integer, l^2 is the number of the father wavelets coeffients 

                         

  h                      m x 1 vector, wavelet basis 

                         

  a                      integer, 0,1,2,3,... see notes 

                         

 Output:



  x                      n x n matrix,
