Interface EquationSolvingAlgorithms.SecantAlgorithm<T,Metadata>

All Known Implementing Classes:

EquationSolvingAlgorithms.SecantDurationAlgorithm

Enclosing class:

EquationSolvingAlgorithms

public static interface EquationSolvingAlgorithms.SecantAlgorithm<T,Metadata>

Solves f(x) = y for x in [xLow, xHigh] with confidence interval [yLow, yHigh] around y such that we stop when value y is in [y-yLow, y+yHigh]. x0 and x1 are initial guesses for x, they must be close to the solution to avoid diverging It is considered that algorithm is diverging when the iterated value of x goes out of [xLow, xHigh].
