+   * 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:
+   *
+   *    math.arg(x)
+   *
+   * Examples:
+   *
+   *    const a = math.complex(2, 2)
+   *    math.arg(a) / math.pi          // returns number 0.25
+   *
+   *    const b = math.complex('2 + 3i')
+   *    math.arg(b)                    // returns number 0.982793723247329
+   *    math.atan2(3, 2)               // returns number 0.982793723247329
