FunctionMath.Integrate(Func<Double, Double, Double>, Double, Double, Double, Double) Method

Numerically integrates a function of two variables over a rectangular region.

Definition

Namespace: Extreme.Mathematics
Assembly: Extreme.Numerics (in Extreme.Numerics.dll) Version: 8.1.23
C# 
public static double Integrate(
	this Func<double, double, double> integrand,
	double xLowerBound,
	double xUpperBound,
	double yLowerBound,
	double yUpperBound
)

Parameters

integrand  Func<Double, Double, Double>
A delegate that represents a function of two variables that specifies the function to integrate.
xLowerBound  Double
The lower limit of the integration region in the X direction.
xUpperBound  Double
The upper limit of the integration region in the X direction.
yLowerBound  Double
The lower limit of the integration region in the Y direction.
yUpperBound  Double
The upper limit of the integration region in the Y direction.

Return Value

Double
An approximation of the definite integral of integrand over a rectangle from xLowerBound to xUpperBound in the X direction, and from yLowerBound to yUpperBound in the Y direction.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type Func<Double, Double, Double>. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
