[SciPy-dev] include fit functions such as erf, exp, cosine etc.

[Matt Fishburn]

Hello,

I recently needed to fit some data to an erf function, but I couldn't 
seem to find one in scipy (I ended up coding one using the outline on 
page 16 of the tutorial).  Are there any functions to fit data to common 
functions such as erf, exp, cosine, and arbitrary degree polynomials, or 
support to include such functions in the future?
