StateTransitionMatrix Methods |
The StateTransitionMatrix type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | AddConsiderParameter |
Adds a consider parameter to the StateTransitionMatrix. Consider parameters can be used when calculating covariance
for a state parameter. The transitions are not actually calculated for a consider parameter, however the values of the consider
parameter do affect those of the state parameters. For example, if you weren't interested in examining how the uncertainty of
the coefficient of drag evolved over time, but were interested in how it's uncertainty affected the uncertainty of the state
parameters, then you would add it as a consider parameter.
|
| AddStateParameter | Adds a state parameter to the StateTransitionMatrix. The state parameters added here make up the state represented by the state transition matrix. The stateDerivative of the stateParameter is needed in order to calculate the derivative of the state transition matrix so that it can be integrated. |
 | CheckForSameDefinition(DefinitionalObject) |
Checks to determine if another instance has the same definition as this instance and
returns if it does. Derived classes MUST override this method and check
all new fields introduced by the derived class for definitional equivalence. It is NOT necessary
to check base class fields because the base class will already have done that. When overriding this method,
you should NOT call the base implementation because it will return for all derived-class instances.
Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).
(Inherited from PropagationStateElement.) |
| CheckForSameDefinition(PropagationStateElement) |
Checks to determine if another instance has the same definition as this instance and
returns if it does. Derived classes MUST override this method and check
all new fields introduced by the derived class for definitional equivalence. It is NOT necessary
to check base class fields because the base class will already have done that. When overriding this method,
you should NOT call the base implementation because it will return for all derived-class instances.
Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).
(Overrides PropagationStateElementCheckForSameDefinition(PropagationStateElement).) |
| CheckForSameDefinition(StateTransitionMatrix) |
Checks to determine if another instance has the same definition as this instance and
returns if it does. Derived classes MUST override this method and check
all new fields introduced by the derived class for definitional equivalence. It is NOT necessary
to check base class fields because the base class will already have done that. When overriding this method,
you should NOT call the base implementation because it will return for all derived-class instances.
Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).
|
| Clone |
Clones this object using the specified context.
(Overrides DefinitionalObjectClone(CopyContext).) |
| ComputeCurrentDefinitionHashCode |
Computes a hash code based on the current properties of this object. Derived classes MUST override this
method and compute a hash code that combines: a unique hash code seed, the base implementation result, and
the hash codes of all new fields introduced by the derived class which are used in the
CheckForSameDefinition(DefinitionalObject) method.
(Overrides PropagationStateElementComputeCurrentDefinitionHashCode.) |
| EnumerateDependencies |
Enumerates the dependencies of this object by calling
EnumerateT(T) for each object that this object directly depends upon.
Derived classes which contain additional dependencies MUST override this method, call the base
implementation, and enumerate dependencies introduced by the derived class.
(Overrides DefinitionalObjectEnumerateDependencies(DependencyEnumerator).) |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| Freeze |
Freezes this object. Further attempts to modify it will result
in an ObjectFrozenException.
(Inherited from DefinitionalObject.) |
| FreezeAggregatedObjects |
Called by Freeze to also freeze any objects that are considered to be a part of this object.
Derived classes which contain additional aggregated objects MUST override this method, call the base
implementation, and freeze aggregated objects introduced by the derived class. The objects that need to be
frozen in this method are frequently created in this object's constructor and are not settable via
properties.
(Overrides DefinitionalObjectFreezeAggregatedObjects.) |
| GetConsiderParameter |
Gets the consider parameter at the specified index which has been added to this StateTransitionMatrix.
|
| GetConverter |
Gets an instance of an output type which can convert the output of propagation
back into the native type of this state element. This method is also responsible
for configuring the state parameter and the state input indices on any parameterized
geometry types used by this element. Each parameterized geometry type will have
a static configuration method which will allow it to configure itself in a particular
EvaluatorGroup.
(Overrides PropagationStateElementGetConverter(EvaluatorGroup, MotionInt32).) |
| GetDefinitionHashCode |
Gets a hash code representing the definition of this object.
(Inherited from DefinitionalObject.) |
| GetDerivatives |
This is used by the NumericalPropagatorDefinition to obtain an instance of a state element evaluator
that can compute the derivatives of this element of the state during propagation.
It cannot be used outside of a NumericalPropagator as the geometry for the propagation state
will be unavailable.
(Overrides PropagationStateElementGetDerivatives(EvaluatorGroup).) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetStateDerivative |
Gets the state derivative at the specified index which has been added to this StateTransitionMatrix.
|
| GetStateParameter |
Gets the state parameter at the specified index which has been added to this StateTransitionMatrix.
|
| GetStateUpdater | Creates an object that will update the state of the StateTransitionMatrix in between propagation steps, if necessary. If TransitionType is PiecewiseTransition then the matrices produced during propagation represent the transition matrices from the previous time step to their own time step. This means that at the beginning of each propagation step the value of the state transition matrix must be reset to the identity matrix. If TransitionType is EpochTransition then the matrices produced during propagation represent the transition matrices from the epoch to their own time step, and this reset is not necessary. |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| IndexOfConsiderParameter |
Searches for the specified considerParameter and returns the index which
can be used to access it via GetConsiderParameter(Int32) or RemoveConsiderParameterAt(Int32).
|
| IndexOfStateDerivative |
Searches for the specified stateDerivative and returns the index which
can be used to access it via GetStateDerivative(Int32) or RemoveStateParameterAt(Int32).
|
| IndexOfStateParameter |
Searches for the specified stateParameter and returns the index which
can be used to access it via GetStateParameter(Int32) or RemoveStateParameterAt(Int32).
|
| IsSameDefinition |
Determines if this object has the same definition as another object.
(Inherited from DefinitionalObject.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
 | PopulateCovarianceCollection |
Transforms an initial covariance matrix forward in time using the given collection of
state transition matrices.
|
| RemoveConsiderParameterAt |
Removes the consider parameter at the given index.
|
| RemoveStateParameterAt |
Removes the state parameter at the given index, as well as its derivative.
|
| ThrowIfFrozen |
Throws ObjectFrozenException if this object IsFrozen.
This method should be called from any method or property that modifies this object.
(Inherited from DefinitionalObject.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
