19 | *
|
20 | * For matrices, the function is evaluated element wise.

|
22 | * Syntax:

25 | *
|
26 | * Examples:
|
27 | *
|
28 | * math.atan(0.5) // returns number 0.4636476090008061
|
29 | * math.atan(math.tan(1.5)) // returns number 1.5
|
30 | *
|
31 | * math.atan(2) // returns Complex 1.5707963267948966 -1.3169578969248166 i
