nAG supplied method for use with the callback parameters: qphx, qphx.

Syntax

C#
public static void e04nku( int nstate, int ncolh, double[] x, double[] hx )

Visual Basic (Declaration)
Public Shared Sub e04nku ( _ nstate As Integer, _ ncolh As Integer, _ x As Double(), _ hx As Double() _ )

Visual C++
public: static void e04nku( int nstate, int ncolh, array<double>^ x, array<double>^ hx )

F#
static member e04nku : nstate:int * ncolh:int * x:float[] * hx:float[] -> unit

nstate: Type: System..::.Int32

On entry: if nstate=1, then e04nku is calling qphx for the first time on a sub-problem. This parameter setting allows you to save computation time if certain data must be read or calculated only once.
If nstate≥2, then e04nku is calling qphx for the last time. This parameter setting allows you to perform some additional computation on the final sub-problem solution. In general, the last call to qphx is made with nstate=2+ (see [Error Indicators and Warnings]).

Otherwise, nstate=0.

ncolh: Type: System..::.Int32

On entry: this is the same parameter ncolh as supplied to e04nku.

x: Type: array< System..::.Double >[]()[]
An array of size [ncolh]

On entry: the first ncolh elements of the vector x.

hx: Type: array< System..::.Double >[]()[]
An array of size [ncolh]

On exit: the product Hx.
