Constructor & Destructor Documentation

◆ BisectionExtremeFinder1D()

BisectionExtremeFinder1D::BisectionExtremeFinder1D ( const FloatMathFunction func,
bool  max,
int  itermax,
float  tol,
const Interval< float > &  startinterval,
const Interval< float > *  limitinterval 
)
Parameters
funcThe function, f(x) where the extreme value shoud be found
maxSpecifies wether a min or max value should be found
itermaxMaximum number of iterations
tolTolerance on the function variable (x)
startintervalThe interval of x that the search will be inited by. Note that the search can go outside of this interval.
limitintervalSet to true if only solutions within the interval is permitted
