Constructor Detail

Interval

public Interval(double leftAbscissa,
                double leftValue,
                double rightAbscissa,
                double rightValue)

Construct a new interval with the given end points.

Parameters:

leftAbscissa - is the abscissa value at the left side of the interval.

leftValue - is the function value at leftAbscissa.

rightAbscissa - is the abscissa value on the right side of the interval. Must be greater than or equal to leftAbscissa.

rightValue - is the function value at rightAbscissa.

Method Detail

getLeftAbscissa

public double getLeftAbscissa()

Get the left abscissa.

Returns:

abscissa of the start of the interval.

getRightAbscissa

public double getRightAbscissa()

Get the right abscissa.

Returns:

abscissa of the end of the interval.

getLeftValue

public double getLeftValue()

Get the function value at getLeftAbscissa().

Returns:

value of the function at the start of the interval.

getRightValue

public double getRightValue()

Get the function value at getRightAbscissa().

Returns:

value of the function at the end of the interval.

getSide

public double getSide(AllowedSolution allowed)

Get the abscissa corresponding to the allowed side.

Parameters:

allowed - side of the root.

Returns:

the abscissa on the selected side of the root.
