hello
im currently working on a cosine curve fit using the fminspleas code, it works out perfectly for the form f(t) = a*cos((x-phi)*(2*pi/T)), where T is the period of my function. the code lets me know a and phi very accurately, but im now in the need to find the function form
f(t) = a*cos((x-phi)*(2*pi/T)) + c... more »

Hi!
I´ve been using yor fminspleas program, which is great, im getting exact result as if i was using te curve fitting tool box, except i encountered a little problem, which i was hopping you could help me out with, im trying to fit a cosine function to a set of data of the form f(t) = a*cos((x-phi)*(2*pi/90)) + C, being C the displacement in the y axis,with the help of fminspleas i´ve gotten a and phi, but now im the necessity to also know C, what would be the best way to generate c?... more »
