QagpIntegrationIntegrate(FuncDouble, Double, Double, Int32, Double, Double, Int32, gsl_integration_rule, Boolean, Double, Double) Method

public GSL_ERROR? Integrate(
	Func<double, double> f,
	double[] pts,
	int npts,
	double epsabs,
	double epsrel,
	int limit,
	gsl_integration_rule integrationRule,
	bool debug,
	out double result,
	out double abserr
)

Parameters

f  FuncDouble, Double

Function to integrate.

pts  Double

Range of integration including the known singular points, see remarks here: QagpIntegration

npts  Int32

Number of valid points in the array pts. Must be less or equal the size of the array pts.

epsabs  Double

Specifies the expected absolute error of integration. Should be set to zero (0) if you specify a relative error.

epsrel  Double

Specifies the expected relative error of integration. Should be set to zero (0) if you specify an absolute error.

limit  Int32

Maximum number of subintervals used for integration.

integrationRule  gsl_integration_rule

Integration rule used for integration (only for this function call).

debug  Boolean

Setting of the debug flag (only for this function call). If the integration fails or the specified accuracy is not reached, an exception is thrown if the debug flag is set to true. If set to false, the return value of the integration function will be set to the appropriate error code (an exception will be thrown then only for serious errors).

result  Double

On return, contains the integration result.

abserr  Double

On return, contains the absolute error of integration.
