Syntax

```public static RetArray<float> besselYn(
InArray<float> x,
int n
)```

#### Parameters

x
Type: ILNumericsInArraySingle
The point where the function will be evaluated.
n
Type: SystemInt32
Integer order of the argument.

#### Return Value

Type: RetArraySingle
The value of the function.
Remarks

• 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, 0.0 will be returned.
• If any element of x is xi == 0.0, double.NegativeInfinity will be returned.
