Standard_EXPORT | math_BracketedRoot (math_Function &F, const Standard_Real Bound1, const Standard_Real Bound2, const Standard_Real Tolerance, const Standard_Integer NbIterations=100, const Standard_Real ZEPS=1.0e-12) |
The Brent method is used to find the root of the function F between the bounds Bound1 and Bound2 on the function F. If F(Bound1)*F(Bound2) >0 the Brent method fails. The tolerance required for the root is given by Tolerance. The solution is found when : abs(Xi - Xi-1) <= Tolerance; The maximum number of iterations allowed is given by NbIterations. . | |
Standard_Boolean | IsDone () const |
Returns true if the computations are successful, otherwise returns false. . | |
Standard_Real | Root () const |
returns the value of 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_Integer | NbIterations () const |
returns the number of iterations really done during the computation of 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. . | |
