Refer to this answer from Star Strider:
You can fit any function using simple least squares regression. Just formulate your function (i guess you have already done that) in matlab, then make a cost function (least squares) and use fminsearch to optimize parameters c1 and c2
P = @(c, t) ... % your function
cost = @(c) sum((P(c,t) - p).^2);
% guess initial parameters
c_guess = [1 1];
% use fminsearch
c = fminsearch(cost, guess);
Cheers

Your code 2 1/2 years ago did not involve fmincon at all, so we cannot guess what your current code looks like.
