Description

Method

BisectionSolver.solve(final UnivariateRealFunction f, double min, double max, double initial)

invokes

BisectionSolver.solve(double min, double max)

which throws NullPointerException, as member variable

UnivariateRealSolverImpl.f

is null.

Instead the method:

BisectionSolver.solve(final UnivariateRealFunction f, double min, double max)

should be called.

Steps to reproduce:

invoke:

new BisectionSolver().solve(someUnivariateFunctionImpl, 0.0, 1.0, 0.5);

NullPointerException will be thrown.
