MtxIntDiff.NumericGradDifference Method

Numerical gradient by numerical differentiation using the forward difference quotient.

Syntax

Visual Basic

public static void NumericGradDifference(TRealFunction Fun, [In] TVec Pars, [In] TVec Consts, [In] object[] ObjConst, [In] TVec Grad);

Parameters

Parameters	Description
TRealFunction Fun	Real function of several variables.
[In] TVec Pars	Function variables.
[In] TVec Consts	Array of additional constants which can be used in math formula.
[In] object[] ObjConst	Array of additional constants (pointers) which can be used in math formula.
[In] TVec Grad	Returns calculated gradient. If needed, Grad Length and Complex properties are adjusted automatically.

Remarks

Calculates the numerical gradient by numerical differentiation using the forward difference quotient. The NumericGradDifference procedure can be used with a very moderate ( >= 1.0e-4) precision requirement.
