I am dealing with a problem of nonlinear curve fitting.

I have estimted samples of a continous fourier transform function, and my goal is to reach from fourier to laplace transform using the known equality: F(S=jw)=laplace{h(t)}.

i want to represnet the laplace trnsform in the following form:

1/(as^2+bs+c), the parameters a, b, c are to be detetmined:

F(jw)*(a(jw)^2+b(jw)+c)=1,

using the eq above in all the freqenqcies F(jw) was estimated.

now i can use the method of nonlinear least squares.

how do i implement this in matlab???

Thx
