Surface Fitting only in Z Direction

I have a 44 by 44 square grid and I have a pressure value specified in the Z direction at each intersection point in the grid. So basically 44 x 44 = 1936 pressure values. I am able to plot a surface for these pressure values but the surface has many peaks. In what way can I smooth the surface? I cannot use cftool since I need to do this for multiple grids. How can I do this automatically by writing a code? I tried using the following syntax:
fitobject = fit([x,y],z,fitType)
But I only want to smooth the surface in Z direction, x and y are distances in space and hence need to be constant. How can I do this?

But you just have a regular grid in x,y. So just use conv2, with a Gaussian blur kernel. Simple to do. Fast. Easy. No need to do any curve or surface fitting.
