Class UnivariateRealSolverImpl

    • Method Detail

      • getResult

        public double getResult()
        Deprecated.
        Get the result of the last run of the solver.
        Specified by:
        getResult in interface UnivariateRealSolver
        Returns:
        the last result.
      • getFunctionValue

        public double getFunctionValue()
        Deprecated.
        Get the result of the last run of the solver.
        Specified by:
        getFunctionValue in interface UnivariateRealSolver
        Returns:
        the value of the function at the last result.
      • setFunctionValueAccuracy

        public void setFunctionValueAccuracy​(double accuracy)
        Deprecated.
        Set the function value accuracy.

        This is used to determine when an evaluated function value or some other value which is used as divisor is zero.

        This is a safety guard and it shouldn't be necessary to change this in general.

        Specified by:
        setFunctionValueAccuracy in interface UnivariateRealSolver
        Parameters:
        accuracy - the accuracy.
      • resetFunctionValueAccuracy

        public void resetFunctionValueAccuracy()
        Deprecated.
        Reset the actual function accuracy to the default. The default value is provided by the solver implementation.
        Specified by:
        resetFunctionValueAccuracy in interface UnivariateRealSolver
      • solve

        public double solve​(int maxEval,
                            UnivariateRealFunction function,
                            double min,
                            double max)
                     throws ConvergenceException,
                            FunctionEvaluationException
        Deprecated.
        Solve for a zero root in the given interval.

        A solver may require that the interval brackets a single zero root. Solvers that do require bracketing should be able to handle the case where one of the endpoints is itself a root.

        Parameters:
        function - the function to solve.
        min - the lower bound for the interval.
        max - the upper bound for the interval.
        maxEval - Maximum number of evaluations.
        Returns:
        a value where the function is zero
        Throws:
        ConvergenceException - if the maximum iteration count is exceeded or the solver detects convergence problems otherwise.
        FunctionEvaluationException - if an error occurs evaluating the function
        java.lang.IllegalArgumentException - if min > max or the endpoints do not satisfy the requirements specified by the solver
        Since:
        2.2

        public double solve​(int maxEval,
                            UnivariateRealFunction function,
                            double min,

                            java.lang.IllegalArgumentException
        Deprecated.
        Solve for a zero in the given interval, start at startValue.

        A solver may require that the interval brackets a single zero root. Solvers that do require bracketing should be able to handle the case where one of the endpoints is itself a root.

        Parameters:
        function - the function to solve.
        min - the lower bound for the interval.
        max - the upper bound for the interval.
        startValue - the start value to use
        maxEval - Maximum number of evaluations.
        Returns:
        a value where the function is zero
        Throws:
        ConvergenceException - if the maximum iteration count is exceeded or the solver detects convergence problems otherwise.
        FunctionEvaluationException - if an error occurs evaluating the function
        java.lang.IllegalArgumentException - if min > max or the arguments do not satisfy the requirements specified by the solver
        Since:
