Hi:

I am trying to fit a non linear equation in two independent variables X1 and X2. The equation looks like
Y = c0 + c1*exp(-c2*X1^2) + c3*exp(-c4*X2^2)

How do I input this function to "lsfitfit" ? The "lsfitcreatef" accepts a real_2d_array for X but the lsfitfit doesn't seem to accept the real_2d_array for user defined function

void lsfitfit(lsfitstate &state,
void (*func)(const real_1d_array &c, const real_1d_array &x, double &func, void *ptr),....

Thanks for your help.

Regards,

Balaji
