Class Description

GSLRootFinderDeriv()


virtual ~GSLRootFinderDeriv()




 GSLRootFinderDeriv(const GSLRootFinderDeriv &)


 usually copying is non trivial, so we make this unaccessible



void SetFunction( const IGenFunction & f, double xlow, double xup)




 SetFunction( f, (xlow + xup)/2. )




void SetFunction( const IGenFunction & f, double Root)




int Iterate()




double Root()




int Solve( int maxIter = 100, double absTol = 1E-3, double relTol = 1E-6)


 Solve for roots



int Iterations()




const char * Name()




void FreeSolver()
