SyntaxC#
public abstract class FitFunctionExeBase : ScriptExecutionBase, IFitFunction
The FitFunctionExeBase type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | FitFunctionExeBase | Initializes a new instance of the FitFunctionExeBase class |
Properties| Name | Description | |
|---|---|---|
 | NumberOfDependentVariables | Number of dependent variables (i.e. y, in Altaxo this is commonly called v like value). |
| NumberOfIndependentVariables | Number of independent variables (i.e. x). |
| NumberOfParameters | Number of parameters of this fit function. |
Methods| Name | Description | |
|---|---|---|
 | CombinePath |
Combines a path with a name to form a full name.
(Inherited from ScriptExecutionBase) |
| DefaultParameterValue | Returns the default parameter value of parameter i. Defaults to return 0. Scripts can override this function in order to provide more useful values. |
| DefaultVarianceScaling | Returns the default variance scaling for dependent variable i. Default returns null, which means a constant weight of 1 is assumed. |
| DependentVariableName | Returns the ith dependent variable name. |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
| Evaluate(Double, Double, Double) | This evaluates a function value. |
| Evaluate(IROMatrixDouble, IReadOnlyListDouble, IVectorDouble, IReadOnlyListBoolean) | Evaluates the function values at multiple x-points. |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) |
| GetHashCode | Serves as the default hash function. (Inherited from Object) |
| GetParameterBoundariesHardLimit | Gets the parameter boundaries that are really a hard limit, i.e. outside those limits, the function would probably evaluate NaN values, or makes no sense. |
| GetParameterBoundariesSoftLimit | Gets the intended parameter boundaries. This are soft limits, boundaries so that the intended purpose of the fit function is fullfilled. Example: in the exponential decay Exp(-a*t) a is intended to be positive. This is a soft limit, and not a hard limit, because a could be also negative, and the fit nevertheless would succeed. |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| IndependentVariableName | Returns the ith independent variable name. |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) |
| OnChanged | Called when anything in this fit function has changed. |
| ParameterName | Returns the ith parameter name. |
| ToString | Returns a string that represents the current object. (Inherited from Object) |
Events
Fields| Name | Description | |
|---|---|---|
 | _dependentVariableNames | The names of the dependent variables. |
| _independentVariableNames | The names of the independent variables. |
| _parameterNames | The names of the parameters. |
