Return Value

Type: RetArrayDouble
The value of the function.

  • If the input x is null, ArgumentNullException will be thrown.
  • If the input x is empty, an empty array will be returned.
  • If the order n is negative, an ArgumentException will be thrown.
  • If any element of x is xi < 0, double.NaN will be returned at that element.
  • If any element of x is xi == double.PositiveInfinity, double.PositiveInfinity will be returned.
  • If any element of x is == 0.0, 0.0 will be returned.
