MoreMathSinc Method

public static double Sinc(
	double x
)

Public Shared Function Sinc ( 
	x As Double
) As Double

public:
static double Sinc(
	double x
)

static member Sinc : 
        x : float -> float 

Parameters

x  Double

The argument.

Return Value

The ratio sin(x) / x, understood to take its limiting value of 1 at x = 0, appears in many applications. This method allows you to compute it straightforwardly without having to implement the limit.

Note that in signal processing applications, the function sin(πx)/(πx) is usually used instead, and is also called the sinc function. Meta.Numerics implements it as SincPi(Double).

This function is also sometimes called the cardinal since function or the sampling function.
