hi
i would like to fit some data X = {{x1,y1},...,{xn,yn}} to a set of
functions, then have this assigned to a function i can call:
fittedfunc[x1] \approx y1
moreover, i need fittedfunc to be as fast as possible in terms of
evaluation, since it will be used in a loop. i think it should be
ideally a compiled function.
i tried
f=Function[x,Fit[X,{functions},x]
bit im finding a major speed hit here, i think every time i call f[x]
it refits the data.
any help would be greatly appreciated.
