How to switch an element in matrix at for example (4,10) to be at (10,4)

Hi

How can i equate an element in a matrix at (x,y) location to a new position at (y,z). I want to interchange the column and row of the element. It will be nice to have it in a for loop

YourMatrix([row1 row2], :) = YourMatrix([row2 row1], :);

exchanges row1 and row2 .

YourMatrix(:, [col1 col2]) = YourMatrix(:, [col2 col1]);

exchange column col1 and column col2.

Try this:

M = randi(9, 4, 5)                              % Create Matrix
R = 2;                                          % Original Row
C = 4;                                          % Original Column
T = M(R,C);                                     % Store Value
M(R,C) = M(C,R);                                % Switch
M(C,R) = T                                      % Output With Switched Elements

Create a loop to do that if you want to switch more elements.
