Hi
i have to solve a polinomio of this form:

Z=A(x^2 y^2) + B(x^2 y) + C(x y^2) + D(x^2) + E(y^2) + F(xy) + Gx + Hy + I

i have all the constants and need to find the value of Z.

How can i do it? exist some function that can solve it?

Hi Mauro,

you need to use leastsq with an error function and jacobian for what you want to optimize.
