A simple matlab code to rotate diagonal

clc;

N=input('number of Row=');

M=input('number of Column=');

X=randi([0,100],N,M);

X(:,2)

Y=X(end:-1:1,end:-1:1);

Final Program:

clc;

N=input('number of Row=');

M=input('number of Column=');

X=randi([0,100],N,M)

X(:,2)

Y=X(end:-1:1, 2)

More Final:

clc;

N=input('number of Row=');

M=input('number of Column=');

X=randi([0,100],N,M)

X(:,2)

Y=X(N:-1:1,2)

 All column rotation to 180

clc;

N=input('number of Row=');

M=input('number of Column=');

X=randi([0,100],N,M)

Y = X(end:-1:1,:,end:-1:1,:)
