functioncwtn
One-dimensional continuous wavelet transform with a given wavelet name
Information
This function carries out one-dimensional CWT transform, same as the function, cwt(). The only difference is that cwtn() receives the wavelet name as input.
Refer to the section of wavelet Families for the detailed information about the available wavelets.
The default input values provide a quick example with a simple saw-tooth signal.
