The other way to calculate the mean is by using rebin. When rebin
shrinks an array, it takes a mean of values. So rather than using:

the general way of doing it is;

mean_image = rebin(myarray,ncols,nrows)

or in your case:

mean_image = rebin(myarray,10,10)

rebin shrinks the array down to new dimensions of size 10x10. It
averages along the third dimension when making the new array.
