Not clear at all.
You can either delete some columns or add some columns, whatever it takes to make the same number of columns as you have rows. If you add new columns, you can put whatever you want in them.
Or you can use interpolation, so a tool like interp2. Of course this a a binary array, so interpolation may not be terribly meaningful. You would then probably want to round the results to convert back to binary.

Try this resizing and see if it does what you want:
squareImage = imresize(rectangularImage, [n, n]);
Otherwise you can crop off the right hand side if m > n
squareImage = rectangularImage(:, 1:n);
or use padarray() or concatenation to add columns if m < n.
blankStrip = zeros(n, m-n+1, class(rectangularImage));
squareImage = [rectangularImage, blankStrip];
It would be good in the future if you thought carefully about what you ask, and phrase it properly, so that we can give you the one single answer you want, and we do not have to guess and give you all possible answers because your question was unclear/ambiguous.
