- 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.
