public GSL_ERROR? Integrate(
	Func<double, double> f,
	double[] pts,
	int npts,
	double epsabs,
	double epsrel,
	int limit,
	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.

result  Double

On return, contains the integration result.

abserr  Double

On return, contains the absolute error of integration.
