Computes the Fresnel cosine and sine integrals.

Declaration Syntax

Visual Basic

Visual C++

public static Complex Fresnel(
	double x
)

Public Shared Function Fresnel ( _
	x As Double _
) As Complex

public:
static Complex Fresnel(
	double x
)

static member Fresnel : 
        x:float -> Complex

Parameters

Return Value

The value C(x) + i S(x).

Remarks

A plot of all values of this function in the complex plane as x ranges from negative infinity to positive infinity is called a Cornu spiral.

The Fresnel function can be related to the complex error function along the line (1-I).
