wavelet instance vs string

[sciunto]

Hi,

In functions.py, intwave and centfreq can receive either a wavelet instance or a string. Should we keep this or should I remove strings as a valid type?

There is the same question for multidim/multilevel actually.

I don't think scipy used to allow two types. @rgommers Thoughts?

There are places in scipy where this happens, for example some functions take a scipy.stats distribution instance or a string with the name of a distribution. I propose to leave it as is for now. If this is done consistently in the same way for the wavelet parameter of functions, I don't mind it actually.

But anyway the complete API needs review before inclusion into scipy, so if we have a list of stuff like this that would be helpful.

Listed as part of overall API review ticket gh-38. So closing this one.
