Nonlinear |
Adapts a FitEnsemble to the requirements of a Levenberg-Marquardt fitting procedure.
This means, the adapter makes the FitEnsemble compatible with the Levenberg-Marquardt algorithm.

public class NonlinearModelOfFitEnsemble : NonlinearObjectiveFunctionNonAllocatingBase
The NonlinearModelOfFitEnsemble type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | NonlinearModelOfFitEnsemble | Constructor of the adapter. |
Properties| Name | Description | |
|---|---|---|
 | DegreeOfFreedom |
Get the degree of freedom
(Inherited from NonlinearObjectiveFunctionNonAllocatingBase) |
| FunctionEvaluations |
Get the number of calls to function.
(Inherited from NonlinearObjectiveFunctionNonAllocatingBase) |
| Gradient |
Get the Gradient vector of x and p.
(Inherited from NonlinearObjectiveFunctionNonAllocatingBase) |
| Hessian |
Get the Hessian matrix of x and p, J'WJ
(Inherited from NonlinearObjectiveFunctionNonAllocatingBase) |
| IsFixedByUser |
Get whether parameters are fixed or free (by the user).
(Inherited from NonlinearObjectiveFunctionNonAllocatingBase) |
| IsFixedByUserOrBoundary |
Array of the length NumberOfParameters. If an element is true, that parameter is either fixed by the user (see IsFixedByUser), or
is fixed because it has reached a boundary.
This array will be updated only at the end of the minimization process.

| IsGradientSupported | (Inherited from NonlinearObjectiveFunctionNonAllocatingBase) |
| IsHessianSupported | (Inherited from NonlinearObjectiveFunctionNonAllocatingBase) |
| JacobianEvaluations |
Get the number of calls to jacobian.
(Inherited from NonlinearObjectiveFunctionNonAllocatingBase) |
| ModelValues |
Get the y-values of the fitted model that correspond to the independent values.
(Inherited from NonlinearObjectiveFunctionNonAllocatingBase) |
| NegativeGradient |
Get the negative gradient vector of x and p.
(Inherited from NonlinearObjectiveFunctionNonAllocatingBase) |
| NumberOfObservations |
Get the number of observations.
(Inherited from NonlinearObjectiveFunctionNonAllocatingBase) |
| NumberOfParameters |
Get the number of unknown parameters.
(Inherited from NonlinearObjectiveFunctionNonAllocatingBase) |
| ObservedY |
Set or get the values of the observations.
(Inherited from NonlinearObjectiveFunctionNonAllocatingBase) |
| Point |
Set or get the values of the parameters.
(Inherited from NonlinearObjectiveFunctionNonAllocatingBase) |
| SigmaSquare |
Gets Chi²/(N-F+1)
(Inherited from NonlinearObjectiveFunctionNonAllocatingBase) |

Methods| Name | Description | |
|---|---|---|
| CopyParametersBackTo | |
| CopyParametersForFitElement | Copies the current parameters for the fit element with the provided index into the provided array. |
| CreateNew | (Overrides NonlinearObjectiveFunctionNonAllocatingBaseCreateNew) |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
| EvaluateAt(IReadOnlyListDouble) | (Inherited from NonlinearObjectiveFunctionNonAllocatingBase) |
| EvaluateAt(VectorDouble) | (Inherited from NonlinearObjectiveFunctionNonAllocatingBase) |
 | EvaluateFunction | (Overrides NonlinearObjectiveFunctionNonAllocatingBaseEvaluateFunction) |
| EvaluateJacobian | (Overrides NonlinearObjectiveFunctionNonAllocatingBaseEvaluateJacobian) |
| EvaluateModelValues(VectorDouble, Boolean) | Calculates the fitting values. |
| EvaluateModelValues(IReadOnlyListDouble, VectorDouble, Boolean) | Calculates the fitting values. |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) |
| Fork | (Overrides NonlinearObjectiveFunctionNonAllocatingBaseFork) |
| GetDependentVariablesInUse | Returns the array of indices of dependent variables that are currently in use (i.e. associated with a data column). |
| GetHashCode | Serves as the default hash function. (Inherited from Object) |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| GetValidNumericRows | Returns the collection of valid numeric rows for the given fit element. |
| GetWeights | Stores the weights for the fit differences in an array. The data are stored from FitElement_0 to FitElement_n. For FitElements with more than one dependent variable in use, the data are stored interleaved. |
| HasToUseWeights | Returns true if any of the fit elements use scaling weights. In this case we have to calculate the weights for all fit elements and include them in the fitting procedures. |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) |
| NumericalJacobian | (Overrides NonlinearObjectiveFunctionNonAllocatingBaseNumericalJacobian(VectorDouble, VectorDouble, Int32)) |
| SetParameters(IReadOnlyListDouble, IReadOnlyListBoolean) |
Set parameters and bounds.
(Inherited from NonlinearObjectiveFunctionNonAllocatingBase) |
| SetParameters(VectorDouble, ListBoolean) |
Set parameters and bounds.
(Inherited from NonlinearObjectiveFunctionNonAllocatingBase) |
| ToObjectiveFunction | (Inherited from NonlinearObjectiveFunctionNonAllocatingBase) |
| ToString | Returns a string that represents the current object. (Inherited from Object) |
