Is it possible to provide initial guesses in cftool?

I've gotten some functions to fit by including the initial guess times one plus a fit parameter. Awkward! An initial guess for each parameter should be an optional field.

It is not currently possible.

I subsequently found that I had overlooked the dialog box in which guesses can be entered (it had been minimize such that I did not see those options). Ignore this whole thread.

Yes, it is possible if using global optimization algorihms (the curve fitting functions built in Matlab, i.e. cftool, lsqcurvefit, are all drived by local optimization algorithms), try Global Optimization Toolbox in Matlab, or other packages like Lingo, 1stOpt, Baron.

Which menu entry should be looked at in cftool?
