Function arg
Compute the argument of a complex value.
For a complex number a + bi, the argument is computed as atan2(b, a).
For matrices, the function is evaluated element wise.
Syntax

Examples
var a = complex(2, 2);
arg(a) / pi; // returns number 0.25
var b = complex('2 + 3i');
arg(b); // returns number 0.982793723247329
atan2(3, 2); // returns number 0.982793723247329
