E04.E04KY_FUNCT2 Delegate
関数リスト一覧 　　NagLibrary Namespaceへ　　ライブラリイントロダクション　　本ヘルプドキュメントのchm形式版

You must supply funct2 to calculate the values of the function Fx and its first derivative ∂F ∂xj  at any point x. It should be tested separately before being used in conjunction with e04ky (see the E04 class).

Syntax

C#
public delegate void E04KY_FUNCT2(
	int n,
	double[] xc,
	out double fc,
	double[] gc
)
Visual Basic (Declaration)
Public Delegate Sub E04KY_FUNCT2 ( _
	n As Integer, _
	xc As Double(), _
	<OutAttribute> ByRef fc As Double, _
	gc As Double() _
)
Visual C++
public delegate void E04KY_FUNCT2(
	int n, 
	array<double>^ xc, 
	[OutAttribute] double% fc, 
	array<double>^ gc
)
F#
type E04KY_FUNCT2 = 
    delegate of 
        n:int * 
        xc:float[] * 
        fc:float byref * 
        gc:float[] -> unit

Parameters

n
Type: System..::.Int32
On entry: the number n of variables.
xc
Type: array< System..::.Double >[]()[]
On entry: the point x at which the function and derivatives are required.
fc
Type: System..::.Double %
On exit: the value of the function F at the current point x.
gc
Type: array< System..::.Double >[]()[]
On exit: gc[j-1] must be set to the value of the first derivative ∂F ∂xj  at the point x, for j=1,2,…,n.
