Standard_EXPORT | math_KronrodSingleIntegration () |
An empty constructor. . | |
Standard_EXPORT | math_KronrodSingleIntegration (math_Function &theFunction, const Standard_Real theLower, const Standard_Real theUpper, const Standard_Integer theNbPnts) |
Constructor. Takes the function, the lower and upper bound values, the initial number of Kronrod points . | |
Standard_EXPORT | math_KronrodSingleIntegration (math_Function &theFunction, const Standard_Real theLower, const Standard_Real theUpper, const Standard_Integer theNbPnts, const Standard_Real theTolerance, const Standard_Integer theMaxNbIter) |
Constructor. Takes the function, the lower and upper bound values, the initial number of Kronrod points, the tolerance value and the maximal number of iterations as parameters. . | |
Standard_EXPORT void | Perform (math_Function &theFunction, const Standard_Real theLower, const Standard_Real theUpper, const Standard_Integer theNbPnts) |
Computation of the integral. Takes the function, the lower and upper bound values, the initial number of Kronrod points, the relative tolerance value and the maximal number of iterations as parameters. theNbPnts should be odd and greater then or equal to 3. . | |
Standard_EXPORT void | Perform (math_Function &theFunction, const Standard_Real theLower, const Standard_Real theUpper, const Standard_Integer theNbPnts, const Standard_Real theTolerance, const Standard_Integer theMaxNbIter) |
Computation of the integral. Takes the function, the lower and upper bound values, the initial number of Kronrod points, the relative tolerance value and the maximal number of iterations as parameters. theNbPnts should be odd and greater then or equal to 3. Note that theTolerance is relative, i.e. the criterion of solution reaching is: Abs(Kronrod - Gauss)/Abs(Kronrod) < theTolerance. theTolerance should be positive. . | |
Standard_Boolean | IsDone () const |
Returns Standard_True if computation is performed successfully. . | |
Standard_Real | Value () const |
Returns the value of the integral. . | |
Standard_Real | ErrorReached () const |
Returns the value of the relative error reached. . | |
Standard_Real | AbsolutError () const |
Returns the value of the relative error reached. . | |
Standard_Integer | OrderReached () const |
Returns the number of Kronrod points for which the result is computed. . | |
Standard_Integer | NbIterReached () const |
Returns the number of iterations that were made to compute result. . | |
