MATLAB Central > MATLAB Newsreader > Angle between two points 

I was wondering how to calculate the angle between two points using matlab, unfortunately this is my first time using matlab and when I input my points I did it individually, ex. x1=2 y1=7, x2=4 y2=9 and x3=4 y3=8. Is there any easy way to calculate the angle formed by those three points?
