how to simulate experimental data with a poly-function (F+G*T...; F G T are non linear functions) and estimate parameters (F(a,b,c,...,x); a b c are parameters and x is the variable Load y(x) with x to MATLAB, and I have the general form y=F+G*T.... with parameters inside, so I want to fit y of the model to experimental data and extract the values of the parameters from this mach

It doesn't change anything that your parameters are now scalars and not vectors. When you use LSQCURVEFIT, you pass all of your parameters bundled into a vector [a,b,c,...] anyway.

Use LSQCURVEFIT if you've got it. Or, one of the functions in the Curve Fit Toolbox.
