Calculate the value of an area around a known co-ordinate

Is it possible to calculate an average of a couple of pixel's value around a known co-ordinate?

I use the following equation:

%%

imtool (Thermal)

P = impixel(Thermal, X,Y)

Is there a wat to get the average of a few pixels around the X,Y instead of just the single value at this point (3 pixels around the X,Y co-ordinate)

mean(Thermal(y-1:y+1,x-1:x+1),'all')

Thank you very much. Just to clarify +1 and -1 is 1 pixel away from either x or y? I could increase this value to include more pixels?

[Matt J]

Yes. You could also use movmean() or conv2() if you wanted the neighborhood means of every pixel.
