There is an easy way to extract a column of a matrix in MATLAB

Suppose you have a matrix A:

A = [1, 2, 3 ; 4, 5, 6]

and you want to swap its first and the second columns.

The following can be done by extracting the first column, storing its value in a temporary variable and replacing second's value with the stored value:

v = A(:, 1);
A(:, 1) = A(:, 2);
A(:, 2) = v;

thanks! helped me as well. I hoped to take the product between the original matrix and a simple binary matrix which would perform the transformation but in my case the matrix is text cell so linear algebra operations are not possible (unless I am missing something)
