Hi all,
            I have a 3 col. data set X=[2.3 4.5 6.7 ...], Y=[....], Z
= [....] of 150 points each and I have a model Z=f(X,Y), with unknown
parameters alpha, beta in it. I want to estimate these two parameters
using the data set.

Any suggestion?

Suggestion #1: Tell us what the model is.

here is the model:

Z=a*log(x+b*y)+exp(-c*x)
-grd'n
.
