How can I compute the four-quadrant inverse tangent using symbolic variables in the Symbolic Math Toolbox?

I want to compute the four-quadrant inverse tangent using symbolic variables.

As of Release 2013a (R2013a), the ATAN2 function in the Symbolic Math Toolbox provides this functionality. For previous product releases, read below for a workaround:

To compute the four-quadrant inverse tangent using symbolic variables created with the Symbolic Math Toolbox, use the ATAN function with two arguments. For example.

a = sym(1);

b = sym(8);

atan(a,b)
