SmDerivative

Assembly: Stat;

Namespace: Prognoz.Platform.Interop.Stat;

Description

The SmDerivative class is used to calculate derivatives.

Comments

This interface can be used to calculate analytical derivatives of expression as well as approximate values of partial derivatives at the specified point. The calculation method is determined with the ISmDerivative.UseAnalyticCalc property.

Fore.NET Syntax

Class to get analog of the SmDerivative class:

None.

Class to get analog of the SmDerivative class object:

SmDerivativeClass;
