-------------------------

Yes but in that one you have to set many other parameters e.g. you have to set the equation by yourself. I am asking something like a curve estimate just like polynomial fitting in Basic Fitting section of Matlab.

I can see in matlab one can fit a st. line or a quadratic curve but why not exponential or logarithmic curve?
