Matlab Question, any experts want to lend a hand?
I'm trying to plot a unit square in Matlab, ie S=[0 1 1 0 0; 0 0 1 1 0].
It should be fairly straightforward, but the graph is shifted over one unit to the right every time I try and plot it, in other words, the origin is at (1,0). What is happening, and is there any way to fix it? I need to rotate the square with rotation vectors and with this quirk it's impossible, the rotated square ends up distorted.
Any help very much appreciated, thanks.

The following matlab code will plot a unit square with vertices (0,0) (1,0) (1,1) (0,1)
vertices = [0 0; 1 0; 1 1; 0 1];
h = patch(vertices(:,1), vertices(:,2), 'w');
axis([-1 2 -1 2])
I have matlab on my computer and have been using it for years
