HELP NEEDED! to fit a linear equation containing 2 independant variables [message #48943]

Dear fellow IDL programmers,

I'm trying to fit the parameters of a linear equation of type:

z = a*x + b*y + c

where a, b,c are constant parameters and x,y are two independant
variables.

In the past, I used the procedures LMFIT, LINFIT, CURVEFIT to fit
equations but these only accept 1 independant variable.

Can someone tell me if a procedure exists to fit the parameters of a
linear equation made of 2 independant variables???

If not, is it possible to give LMFIT, LINFIT, CURVEFIT...etc. 2
independant variables instead of only 1?

Thanks a lot !!!
Tony
