Not sure what that means, but how about the line() function? Or imline()?

Regarding your "Answer", which should have been a comment to me here: you can use line() with preassigned coordinates. It does not have to be drawn manually - not sure why you thought that. Just figure out where they should be placed, and call line(x, y).

Yes, if I put in line() x and y coordinates, I get preassigned coordinates, but I need, that then I open new image, coordinates draw automaticaly, and I would not need to enter coordinates manually.

Not sure what you're saying. Are you saying that you don't have the coordinates? If so you should have asked how to find the symmetry axis, rather than how to add it (which implies, at least to me, that you want to add a line along the axis which you've already identified).

I'm sorry, it's my fault, I need to find image symmetry axis.

I don't have any code for that. It could be complicated if the head is tilted with respect to the shoulders or turned so that it's not looking directly along the optic axis. Thus I suggest you find an algorithm here: http://iris.usc.edu/Vision-Notes/bibliography/contentspeople.html#Face%20Recognition,%20Detection,%20Tracking,%20Gesture%20Recognition,%20Fingerprints,%20Biometrics I'm sure someone must have done this before and you can find their papers there.

I need that matlab draw symmetry axis on the face in the image like in attach file, i try to use line(), and imline() functions, but with these functions I can draw only manually, how to do that lines draw automatically?

Maybe someone else have any ideas, how to do face symmetry axis?
