Differences Of The Elements Of A Matrix.

Hi, I have a problem which may be very simple for others but since I am very new to MATLAB I am facing some problem regarding the same.

I have a 128-by-128 matrix. I need to find the differences of the adjacent elements(i.e., 2nd element- 1st element,3rd element- 2nd element...so on),firstly along the rows and secondly along the columns to give two different matrices(using the 'diff'command). Can anyone please help me out in solving this problem?

Thanking You!

doc diff

eg:

H = diff(I,1,2) % differences between columns

V = diff(I) % differences between rows
