I have two points in a image. I want to fix coordinates of the two points and convert them into polar coordinates. My intention is to find the angle made by the vector joining these two points.

angle = atan2d((y2-y1)/(x2-x1));

How do you tell where the points are? Is there something distinctive about the points that you search for in the image? Or are you wanting the user to click on the points? If that is the case look at ginput()

You said "I have two points in a image" so I assume that you already specified them in some way that you did not tell us about.
