MATLAB: Finding a median of a matrix in form of a matrix

Question

How could I turn a vector such as: [0 0 1 1 1 0 0]

Into: [0 0 0 1 0 0 0]

The actual matrix im dealing with is about 100×300 so I'd need something that I could maybe put into a 'for' loop in order to do all columns one-by-one.

Thank you in advance!

Edit:

My current code, until a better solution comes along, is:

s = size(graph);
for column = 1:s(2)
    I = find(graph(:,column) == 1);
    if I>0
        place = median(I);
        place = round(place);
        graph(:,column) = 0;
        graph(place,column) = 1;
    end
end

I'm sure it's really not the best way to do it, I put it in place just for the moment so I can continue with the project.
