On an earlier StackExchange question, I read that for a given signal, "From the resulting DWT the corresponding full CWT can be obtained by convolving the DWT with the reproducing kernel of the respective wavelet. The reproducing kernel is the CWT of the wavelet itself." (see here)
Could someone explain this in a bit more practical detail please?
Does Python or MATLAB have a function that does this? Also, if someone could point to some reading on this specific question, that would be great.
