A = eye(10)

A = 10×10

1 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 1

A = circshift(A(3,:),1)

A = 1×10

0 0 0 1 0 0 0 0 0 0

You can use circshift function to shift position of zeros in the matrix as above

In the above e..g matrix, elements of 3rd row in the matrix A is shifted by 1 step, Similarly if you want to shift 2 steps use

A = circshift(A(3,:),2)

Can we put in for loop to shift whole matrix ?

[Jenifer NG]

a = [255	255	255	0	255
255	255	0	255	255
255	0	255	255	255
255	0	255	255	255
255	255	0	255	255
255	255	255	0	255
]

n = length(a)

for i = 1:n
    if i<=3
        b{i} = circshift(a(i,:),i)
    else
        b{i} = circshift(a(i,:),7-i)
    end

end
