4. Matlab Matrix Shifting
*B = circshift(A, shiftsize) circularly shifts the values in the array, A, by shiftsize elements
>> A=[1 2 3; 4 5 6; 7 8 9]
A =
1 2 3
4 5 6
7 8 9
>> B=circshift(A,1)
B =
7 8 9
1 2 3
4 5 6
>> B=circshift(A,[1,-1])
B =
8 9 7
2 3 1
5 6 4
>> B=circshift(A,[1,1])
B =
9 7 8
3 1 2
6 4 5
