how can i rotate a matrix? in matlab

In Matlab, you can use the "rot90" function to rotate a matrix clockwise by 90 degrees. You can call this function multiple times to rotate the matrix by 180 or 270 degrees.

Here is an example code snippet to rotate a matrix by 90 degrees:

main.m
% Input matrix
A = [1, 2, 3; 4, 5, 6; 7, 8, 9];

% Rotate matrix by 90 degrees
B = rot90(A);

% Display rotated matrix
disp(B);
128 chars
9 lines

The output of this code will be:

main.m
B =
     3     6     9
     2     5     8
     1     4     7
61 chars
5 lines

You can also use the "transpose" function followed by a "flip" to rotate a matrix:

main.m
% Input matrix
A = [1, 2, 3; 4, 5, 6; 7, 8, 9];

% Rotate matrix by 90 degrees
B = flip(transpose(A));

% Display rotated matrix
disp(B);
138 chars
9 lines

The output of this code will be:

main.m
B =
     3     6     9
     2     5     8
     1     4     7
61 chars
5 lines

Note that the "flip" function flips the matrix along the specified dimension. In this case, we are flipping along the first dimension (rows) to achieve a clockwise rotation.
