If you search Google for " inverse continuous wavelet transform VI", you will get a number of hits that are not quite what you are aslking about, but I don't know enough about wavelets and their associated math to know if any of the results such a search returns are applicable.
The other approach you might take is to look at the Matlab code -- if there is a function (expressed as a m-file) for the function you need, you can either (a) call it as a MathScript item (I have no recent experience with this, I haven't used Matlab since I learned LabVIEW) or (b) recode the algorithm (assuming it can be reduced to calls to Matlab ".m" code) in a LabVIEW VI (or a series of nexted VIs). I recently undertook exactly such a project involving analyzing "Learning" of a behavioral task. The LabVIEW version of the algorithm (a) gave effectively the same "Learning Curve" as the Matlab implementation, (b) was easier to walk through and explain what is happening in the generation of the learning curve (and simplifies the "how" it happens), and (c) permitted other data types than 2D Arrays of Float.
