I have been struggling with defining a custom wavelet using pywavelets. I would like to perform a DWT using the ricker wavelet. However, the ricker wavelet does not seem to be part of the in-built wavelet family provided by pywavelets. The official pywavelet documentation gives an example illustrationg how to define a custom Haar wavelet. http://www.pybytes.com/pywavelets/ref/wavelets.html Since a functional form needs to be put in for the Ricker wavelet, I have been unable to build upon this example to create a custom Ricker wavelet using pywavelets.
