You can use line and swap the Y-coordinate values to get the perpendicular line:

line([2 5],[3 7])
hold on
line([2 5],[7 3])
axis square
hold off

Why is this tagged Bresenham? Do you have a digitized "canvass" that you have to draw this on? If not, then the line() function will draw continuous lines with no gaps and you don't have to worry about Bresenham. If you have an image and you want to "burn it into" the image, then you could use Bresenham but you don't have to because imline() will do it for you.
