Lev |
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 LevMarAdapter
The LevMarAdapter type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | LevMarAdapter | Constructor of the adapter. |
Properties| Name | Description | |
|---|---|---|
 | CovarianceMatrix | Gets the covariance matrix. The covariance matrix has always a dimension of n x n, with n the number of varying parameters. |
| NumberOfData | Number of total valid data points (y-values) of the fit ensemble. This is the array size you will need to store the fitting functions output. |
| ResultingChiSquare | |
| ResultingSigmaSquare |
Methods| Name | Description | |
|---|---|---|
| CanUseJacobianVersion | This function determines, wheter or not all fit functions provide the jacobians. In this case, the fitting procedure can make use of the jacobian. |
| CopyParametersBackTo | |
| DoSimplexMinimization | |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
| EvaluateChiSquare | |
| EvaluateFitDifferences | Provides an adapter for the NLFit.LMFunction interface. |
| EvaluateFitJacobian | Calculates the jacobian values, i.e. the derivatives of the fitting values with respect to the parameters. |
| EvaluateFitValues(Double, Boolean) | Calculates the fitting values with the currently set parameters. |
| EvaluateFitValues(Double, Double, Boolean) | Calculates the fitting values. |
| EvalulateFitValues | 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) |
| Fit | |
| Fit1 | |
| Fit2Jac | Can only be used, if all fit functions provide the jacobian. |
| GetDependentValues | Stores the dependent values of all elements 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. |
| 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) |
| GetParameters | Copies the current parameters for the fit element with the provided index into the provided array. |
| 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) |
| ToString | Returns a string that represents the current object. (Inherited from Object) |
