Hi I have a matrix
A=[1 2 3;
4 5 6;
7 8 9]
but I want to switch the first column with first line like this
A=[1 4 7;
2 5 6;
3 8 9].
What it's the fast way to do it? Any help is appreciated! Thank you

If only the 1st column and row are involved, e.g. a simple swap:
A1 = A(:,1);
A(:,1) = A(1,:);
A(1,:) = A1;
