Hello, I have extracted the data from two graphs. Let's say one is X vs Z with constant Y and the other is Y vs Z with constant X. I have plotted a 3D graph for the same. Now I need a function describing the relation between the 3 variables. I am uploading a sample file along with this question. How do I determine which curve fits the best and the equation for the same?

If you have the Curve Fitting Toolbox , you could try interactive surface fitting .
If you don't have it, you could try polyfitn, which you can download from the File Exchange.
