Smoothing 2D matrix

Hi,

I have a 2D matrix data as shown in surf plot below. It has lots spikes or noise even after 2dinterpolation.But I want to smooth it and I could not find any funtion/code to make it smoother. I am looking forward to your comments as soon as possible. Thanks.

May be using this would work:

Where A is 2D matrix and FilterSize can be changed to control smoothenig you want.

imgaussfilt(A,'FilterSize',3); 

Other option can be to use fspecial function.
