MoreMathSinc Method

Computes the sinc function.

Namespace:  Meta.Numerics
Assembly:  Meta.Numerics (in Meta.Numerics.dll) Version: 4.1.4
public static double Sinc(
	double x


Type: SystemDouble
The argument.

Return Value

Type: Double
The value of sinc(x) = sin(x) / x.

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.
