static Standard_Boolean	KronrodPointsAndWeights (const Standard_Integer Index, math_Vector &Points, math_Vector &Weights)
	Returns a vector of Kronrod points and a vector of their weights for Gauss-Kronrod computation method. Index should be odd and greater then or equal to 3, as the number of Kronrod points is equal to 2*N + 1, where N is a number of Gauss points. Points and Weights should have the size equal to Index. Each even element of Points represents a Gauss point value of N-th Gauss quadrature. The values from Index equal to 3 to 123 are stored in a table (see the file math_Kronrod.cxx). If Index is greater, then points and weights will be computed. Returns Standard_True if Index is odd, it is equal to the size of Points and Weights and the computation of Points and Weights is performed successfully. Otherwise this method returns Standard_False.

static

Returns a vector of Kronrod points and a vector of their weights for Gauss-Kronrod computation method. Index should be odd and greater then or equal to 3, as the number of Kronrod points is equal to 2*N + 1, where N is a number of Gauss points. Points and Weights should have the size equal to Index. Each even element of Points represents a Gauss point value of N-th Gauss quadrature. The values from Index equal to 3 to 123 are stored in a table (see the file math_Kronrod.cxx). If Index is greater, then points and weights will be computed. Returns Standard_True if Index is odd, it is equal to the size of Points and Weights and the computation of Points and Weights is performed successfully. Otherwise this method returns Standard_False.

static Standard_Integer math::KronrodPointsMax ( )

static

Returns the maximal number of points for that the values are stored in the table. If the number is greater then KronrodPointsMax, the points will be computed.

static Standard_Boolean math::OrderedGaussPointsAndWeights ( const Standard_Integer  Index, math_Vector &  Points, math_Vector &  Weights  )

static

Returns a vector of Gauss points and a vector of their weights. The difference with the method GaussPoints is the following:

• the points are returned in increasing order.
• if Index is greater then GaussPointsMax, the points are computed. Returns Standard_True if Index is positive, Points' and Weights' length is equal to Index, Points and Weights are successfully computed.
