## AdaptiveNumericalIntegrator Properties |

The AdaptiveNumericalIntegrator type exposes the following members.

Properties

Name | Description | |
---|---|---|

AdaptiveWeights |
Gets or sets the weights to be applied to the state elements when
computing the error which determines how to adapt the step size.
This is in addition to any weights used in the integration algorithm
itself. If these weights have not been initialized before
Initialize(Double, Double) is called, they will be set to a default value
of one.
| |

CurrentStepSize |
Gets the current (positive) size of the step which the integrator will use for the next integration step.
(Overrides NumericalIntegratorCurrentStepSize.) | |

Dimension |
Gets the number of dependent variables based on the
Dimension of the SystemOfEquations.
(Inherited from NumericalIntegrator.) | |

Direction |
Gets or sets whether to integrate forward, increasing the independent variable, or backward,
decreasing the independent variable.
(Inherited from NumericalIntegrator.) | |

FinalDependentVariableValues |
Gets or sets the values of the dependent variables resulting from the last integration step.
(Inherited from NumericalIntegrator.) | |

FinalIndependentVariableValue |
Gets or sets the value of the independent variable after an integration step.
(Inherited from NumericalIntegrator.) | |

InitialDependentVariableValues |
Gets or sets the values of the dependent variables prior to an integration step.
These values will be updated to the previous FinalDependentVariableValues
at the beginning of each integration step.
(Inherited from NumericalIntegrator.) | |

InitialIndependentVariableValue |
Gets or sets the value of the independent variable prior to an integration step.
(Inherited from NumericalIntegrator.) | |

InitialStepSize |
Gets or sets the initial (positive) size of the step to add to the InitialIndependentVariableValue
when performing an integration. By default, the initial value is one.
(Inherited from NumericalIntegrator.) | |

IsThreadSafe |
Gets a value indicating whether the methods on this instance are safe to call from
multiple threads simultaneously.
(Inherited from NumericalIntegrator.) | |

Iterations |
Gets or sets the number of iteration required to adapt the CurrentStepSize to
within error tolerance.
| |

MaximumIterations |
Gets or sets the maximum number of Iterations to allow before forcing the integrator
to accept the CurrentStepSize and proceed to the next step.
| |

MaximumStepSize |
Gets or sets the maximum size of the CurrentStepSize.
| |

MinimumStepSize |
Gets or sets the (positive) minimum size of the CurrentStepSize.
| |

PreviousStepSize |
Gets the size of the last step taken by the integrator. This returns the difference between the
FinalIndependentVariableValue and the InitialIndependentVariableValue.
(Inherited from NumericalIntegrator.) | |

StepDeflationExponent |
Gets or sets the exponent to apply to the error when calculating the amount to decrease the size of the step.
| |

StepDeflationFactor |
Gets or sets a scalar multiplier to apply to the step when decreasing it.
| |

StepInflationExponent |
Gets or sets the exponent to apply to the error when calculating the amount to increase the size of the step.
| |

StepInflationFactor |
Gets or sets a scalar multiplier to apply to the step when increasing it.
| |

StepSizeBehavior |
Gets or sets whether to avoid adapting the step size and instead fix the value of CurrentStepSize.
| |

StepSizeInformation |
Gets or sets a value indicating whether the CurrentStepSize was changed from the InitialStepSize
and, if so, the nature of how it was changed.
(Inherited from NumericalIntegrator.) | |

StepTruncationOrder |
Gets or sets the integer exponent specifying the order of magnitude at which to
truncate the significant digits in the CurrentStepSize. For instance,
to truncate the value to three decimal places, specify a truncation order of -3.
To truncate the value to an order of 100, specify a truncation order of 2. To specify
the step size should be an integer value, specify a truncation order of 0.
| |

SystemOfEquations |
Gets or sets the system of differential equations corresponding to the derivatives of the
dependent variables.
(Inherited from NumericalIntegrator.) |
