Suppose I have a matrix of 13*13 and I would like to copy column 1 of this matrix to column 2 of the same matrix , how can I carry out this copying operation?

Thank you in advance.

res = circshift(mat, [0 -1]); % mat assumed as your matrix

mat = [zeros(size(mat, 1),1), mat] % Append zeros as first column,

Thank you for the answer, but I would like to copy the elements of first column to the second without any changes in the first column (both the columns belong to same matrix) . I don't want to create a new matrix.
