The MATLAB function "waverec" should perform the inverse operation of "wavedec"

Sandeep Singh Sengar

You can use wavedec3 (X, n, w) for multi level decomposition.

Here n-number of label, w-wavelet name, and X-data

Hameed R. Farhan

You can use the function waverec3 to reconstruct the results of the function wavedec3 as follows:

waverec3(WDEC,TYPE,N)
