Description:
The trigonometric functions are scalars functions. The return
value is the result of the trigonometric operation performed
on the input, element-by-element.
{\bf atan2} returns the arctangent of $A/B$.
All the trigonometric functions use the C language math
library functions, so details about the ranges and error
conditions can be found by examining the appropriate man pages
on your system.
Atan2 does not operate on complex arguments.
