The WV_IMPORT_WAVELET procedure allows the user to add wavelet functions to the currently-active IDL Wavelet Toolkit(s).
WV_IMPORT_WAVELET [, Wavelet] [, /RESET]
A string scalar or vector giving the names of the wavelet functions. The actual function names are constructed by removing all white space from each name and attaching a prefix of WV_FN_.
If set, then remove all user-defined wavelets from memory. If Wavelet is also specified then the new wavelets will be appended onto the built-in wavelets.
