Standard_EXPORT | math_BissecNewton (math_FunctionWithDerivative &F, const Standard_Real Bound1, const Standard_Real Bound2, const Standard_Real TolX, const Standard_Integer NbIterations=100) |
A combination of Newton-Raphson and bissection methods is done to find the root of the function F between the bounds Bound1 and Bound2. on the function F. The tolerance required on the root is given by TolX. The solution is found when : abs(Xi - Xi-1) <= TolX and F(Xi) * F(Xi-1) <= 0 The maximum number of iterations allowed is given by NbIterations. . | |
virtual Standard_EXPORT Standard_Boolean | IsSolutionReached (math_FunctionWithDerivative &F) |
This method is called at the end of each iteration to check if the solution has been found. It can be redefined in a sub-class to implement a specific test to stop the iterations. . | |
Standard_Boolean | IsDone () const |
Tests is the root has been successfully found. . | |
Standard_Real | Root () const |
returns the value of the root. Exception NotDone is raised if the minimum was not found. | |
Standard_Real | Derivative () const |
returns the value of the derivative at the root. Exception NotDone is raised if the minimum was not found. | |
Standard_Real | Value () const |
returns the value of the function at the root. Exception NotDone is raised if the minimum was not found. | |
Standard_EXPORT void | Dump (Standard_OStream &o) const |
Prints on the stream o information on the current state of the object. Is used to redifine the operator <<. . | |
