This is an example of using a custom example with fit using a function.

I seem to have trouble applying it with two variables z(x,y).

Hi Xymbu,
I understand that you want to find how to model a custom surface equation defined by two variables.
Please follow the below steps to achieve it.
1. Open the Curve Fitter app by entering the command “curveFitter” in the command window.
2. Create three variables, “x”, “y”, and “z” in the workspace.
3. On the “Curve Fitter” tab, in the “Data” section, click “Select Data”. In the dialog, select the corresponding variables that you have defined in the workspace.
4. Now, in the “Fit Type” section, select “Custom equation” option.
5. In the “Custom Equation” tab that opens to the right, you can define the surface equation.
To learn more about curve fitting, please refer to the following links.

I hope this solution works for you.
Thanks,
Ravi Chandra
