Hi everyone,

I have a very complicated function y with only one independent variable x, and want to fit or approximate it by a simpler function, say polynomial. Many books or maple reference seem to tell how to fit a set of data instead of a given function. But the argument x in the function is assumed to be continuous other than discrete, so I don't know whether it is possible to express datax in form of x's range such as 0..1, and express datay in form of the function. After that , maybe I can fit the two created data sets by a polynomial function.

Or, does anyone have a better or more direct way to do the fitting linking two fucntions?

I am appreciated for your help.

Best,

GOODLUCK

Hello, everyone. I have been messed up by a system of 50 nonlinear parametric equations with 50 unknowns(see the code in the file named nonlinear ). Since I am new to Maple, I don't know whether it is possible to make such a system work out by software. I've tried the SOLVE and FSOLVE command but get no result. Are there any other ways or toolbox for such kind of systems? Is there any typing wrongs in my code? I am sincerely looking forward to  receive any ideas...
