Hi everyone! I have some experimental data and I have to fit it. Hi want to use a specific function, i.e y(x) = (C*x^a)/Gamma(1-a)), where C and a are constants, and Gamma is the Euler Gamma function.
If I use fit function, I cannot use my favorite form. How can I do this? Thanks a lot for your answer :)

i think 'lsqnonlin' is best suited...
if you dont want to minimize least squares, you can write your own objective function and use 'fminunc' (or fminsearch if you dont have the optimization toolbox)
