How can we slide say a 3X3 window on a matrix and perform an operation (i.e. Sum) on the 3X3 window, and then move that 3X3 window to the next part until we reach the end of the matrix? Thanks.

You can use conv2():
blurredImage = conv2(double(grayImage), ones(3), 'same');
imshow(blurredImage, []);
You could also use imfilter(). Use ones(3)/9 if you want the average instead of the sum.
