I have some data to which I want to fit the following function:
c1 * X + c2 * Y
I know the values for X and Y, can you give me a hint as to how I should proceed?

Thanks for the hint! As ou can see in the screenshot, I think the only problem is I'd need to specify the function as f(X,Y), but for some reason I can only specifcy it as f(X):

You can launch the Curve Fitting Tool with 'cftool( x, y, z )' for your case. This will create a surface fit to x and y inputs and z output.
