Like this:
figure;
hold on;
imagesc(img);
line([x1,x2],[y1,y2],'Color','r','LineWidth',2)
hold off
Where y is the "down" direction and x is the "right" direction in the image. Change the color and width as necessary to be visible.
load clown
image(X)
colormap(map)
c = size(X,2)
mid = round(c/2)
X(:,mid) = 1
image(X)
You could download and use hline and vline in conjunction with hold on, using the techniques from visiting Steve on Image Processing. Or just use his techniques. Either way it works.
