functionwavRec
Wavelet multilevel reconstruction
Information
This function transforms the wavelet coefficients, which are obtained with multi-level wavelet decomposition, back to the original signal. The definitions of the input parameters, c and len, are same as the function wavDec().
Refer to the section of wavelet Families for the detailed information about the available wavelets.
The default input values provide a quick example to generate a simple saw-tooth signal.
