I am having 7*7 matrix. Now i need to rearrange the matrix colums in such a way that last column of the matrix will be considered first column and first column as second, second column as third and so on.

Example:

A=[0 0 0 1 0 0 0

0 1 0 0 0 0 0

0 0 0 0 1 0 0

1 0 0 0 0 0 0

0 0 0 0 0 1 0

0 0 1 0 0 0 0

0 0 0 0 0 0 1]

Expected output:

Example:

B=[0 0 0 0 1 0 0

0 0 1 0 0 0 0

0 0 0 0 0 1 0

0 1 0 0 0 0 0

0 0 0 0 0 0 1

0 0 0 1 0 0 0

1 0 0 0 0 0 0]
