you can use impoint, for example:

figure, imshow('pout.tif');
h = impoint(gca,[]);
position = wait(h);

this interactively place a point. Use wait to block the MATLAB command line. Double-click on the point to resume execution of the MATLAB command line. position is specifying the coordinates of the point [X Y].
