public interface IFitFunctionWithDerivative : IFitFunction
The IFitFunctionWithDerivative type exposes the following members.
Properties| Name | Description | |
|---|---|---|
 | NumberOfDependentVariables |
Number of dependent variables (i.e. y, in Altaxo this is commonly called v (like value)).
(Inherited from IFitFunction) |
| NumberOfIndependentVariables |
Number of independent variables (i.e. x).
(Inherited from IFitFunction) |
| NumberOfParameters |
Number of parameters of this fit function.
(Inherited from IFitFunction) |
Methods| Name | Description | |
|---|---|---|
 | DefaultParameterValue |
Returns a default parameter value. You must ensure that the fit function would generate
values with those default parameters.
(Inherited from IFitFunction) |
| DefaultVarianceScaling |
Returns the default variance scaling for the dependent variable i.
(Inherited from IFitFunction) |
| DependentVariableName |
Returns the ith dependent variable name.
(Inherited from IFitFunction) |
| Evaluate(Double, Double, Double) |
This evaluates a function value.
(Inherited from IFitFunction) |
| Evaluate(IROMatrixDouble, IReadOnlyListDouble, IVectorDouble, IReadOnlyListBoolean) |
Evaluates the function values at multiple x-points.
(Inherited from IFitFunction) |
| EvaluateDerivative | This evaluates the gradient of the function with respect to the parameters. |
| 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.
(Inherited from IFitFunction) |
| 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.
(Inherited from IFitFunction) |
| IndependentVariableName |
Returns the ith independent variable name.
(Inherited from IFitFunction) |
| ParameterName |
Returns the ith parameter name.
(Inherited from IFitFunction) |
Events| Name | Description | |
|---|---|---|
 | Changed |
Occurs when the fit function changed, including number or name of parameters, independent variables, dependent variables, or the scaling.
