Remove duplicate 1s from matrix columns

Suppose I have the following logical matrix,

qq =

  3×5 logical array

   1   0   1   1   1
   1   1   0   1   1
   1   0   0   0   1

I'm trying to write a few lines which would allow me to set each column to possess only a single 1 by setting additional 1s to 0. The output should look like the following.

qq =

  3×5 logical array

   1   0   1   1   1
   0   1   0   0   0
   0   0   0   0   0

Mitchell, try this:

qq = logical([...
   1   0   1   1   1
   1   1   0   1   1
   1   0   0   0   1])
[rows, columns] = size(qq);
for col = 1 : columns
	highestOne = find(qq(:, col), 1, 'first');
	if ~isempty(highestOne)
		qq(highestOne + 1 : end, col) = false;
	end
end
qq % Show in command window.

You see:

qq =

3×5 logical array

1 0 1 1 1

1 1 0 1 1

1 0 0 0 1

qq =

3×5 logical array

1 0 1 1 1

0 1 0 0 0

0 0 0 0 0

Looks good, but I was looking for something vectorised. Apologies, I should've specified that.

And I gave it to you. Saying qq(:, col) means to get the column vector from the matrix.
