Class FixedIntervalIntegrator

  • All Implemented Interfaces:
    Serializable, Descriptive, Reflexive
    Direct Known Subclasses:
    MidpointIntegrator, SimpsonIntegrator
    public abstract class FixedIntervalIntegrator
extends AbstractIntegrator
    A fixed-interval integrator implements a numerical scheme in which the domain within the integration bounds is divided into equal intervals of a sufficiently small (and fixed) length. The integral is then approximately equal to the sum of the integrand function values at the nodes resulting from such partitioning times the integration weights.

    • Constructor Detail

      • FixedIntervalIntegrator

        public FixedIntervalIntegrator​(Segment bounds)
        Creates a FixedIntervalIntegrator with the specified integration bounds and a default number of integration segments.
        Parameters:
        bounds - the integration bounds

      • FixedIntervalIntegrator

        public FixedIntervalIntegrator​(Segment bounds,
                               NumericProperty segments)
        Creates a FixedIntervalIntegrator with the specified integration bounds number of integration segments.
        Parameters:
        bounds - the integration bounds
        segments - number of integration segments

    • Method Detail

      • getIntegrationSegments

        public NumericProperty getIntegrationSegments()
        Retrieves the number of integration segments.
        Returns:
        the number of integration segments.

      • setIntegrationSegments

        public final void setIntegrationSegments​(NumericProperty integrationSegments)
        Sets the number of integration segments and re-evaluates the integration step size.
        Parameters:
        integrationSegments - a property of the INTEGRATION_SEGMENTS type

      • setBounds

        public final void setBounds​(Segment bounds)
        Sets the bounds to the argument and re-evaluates the integration step size.
        Overrides:
        setBounds in class AbstractIntegrator
        Parameters:
        bounds - the integration bounds

      • set

        public void set​(NumericPropertyKeyword type,
                NumericProperty property)
        Description copied from class: Accessible

        An abstract method, which must be overriden to gain access over setting the values of all relevant (selected by the programmer) NumericProperties in subclasses of Accessible. Typically this involves a switch statement that goes through the different options for the type and invokes different set(...) methods to update the matching NumericProperty with property.

        Specified by:
        set in class Accessible
        Parameters:
        type - the type, which must be equal by definition to property.getType().
        property - the property, which contains new information.

      • listedKeywords

        public Set<NumericPropertyKeyword> listedKeywords()
        The listed property is INTEGRATION_SEGMENTS.
        Overrides:
        listedKeywords in class PropertyHolder
        Returns:
        a set of NumericPropertyKeyword instances, which have been explicitly marked as a listed parameter for this PropertyHolder.

      • stepSize

        public final double stepSize()
        Retrieves the step size equal to the integration range length divided by the number of integration segments.
        Returns:
        the integration step size.
