How can I graph a set of polar coordinates with unique origins?

I have a set of points in the format x, y, r, Θ. At each point (x, y), there is a radius pointing out of distance r in direction Θ. Is there an easy method to graph these points directly without converting to Euclidean coordinates?

No. But at least you can do them all at the same time.

starts = [x(:), y(:)];
[rx, ry] = pol2cart(theta(:), r(:));
ends = starts + [rx, ry];

and then you have to plot them. A trick for that:

xlist = [starts(:,1), ends(:,1), nan(size(starts,1),1)] .';
ylist = [starts(:,2), ends(:,2), nan(size(starts,1),1)] .';
plot( xlist(:), ylist(:) );

If you have a rectangular grid of these points then see quiver()
