sftool with X and Y axis of not the same lengths

Hi all, I am new to sftool. i have x=1:14 and y=1:16. In addition i have the measured data z (14x16). I am trying to model the behavior of z as function of x and y. I tried sftool but i always get this error :X, Y and Z must be the same length.

 x, y and z are set as columns z=z(:) x=x(:) and y=y(:).

I don't what to do!!

Thank you for you help in advance.
