Look at the circle quadrants in this link: http://www.mathworks.com/help/matlab/ref/atan2.html

The "atan2" presents the angle between x and y. But if you have one input (Y), you can use "atan" block only.

Rene Galindo

atan2(y,x) = inverse tangent of (y/x), however, it takes into account the quadrant of the resulting angle. For instance atan2(-1,-1) = -135 y atan2(1,1) = 45
