fcn must return the values of the functions fi at a point x.

Syntax

C#
public delegate void C05QB_FCN(
	int n,
	double[] x,
	double[] fvec,
	ref int iflag
)
Visual Basic
Public Delegate Sub C05QB_FCN ( _
	n As Integer, _
	x As Double(), _
	fvec As Double(), _
	ByRef iflag As Integer _
)
Visual C++
public delegate void C05QB_FCN(
	int n, 
	array<double>^ x, 
	array<double>^ fvec, 
	int% iflag
)
F#
type C05QB_FCN = 
    delegate of 
        n : int * 
        x : float[] * 
        fvec : float[] * 
        iflag : int byref -> unit

Parameters

n
Type: System..::..Int32
On entry: n, the number of equations.
x
Type: array<System..::..Double>[]()[][]
On entry: the components of the point x at which the functions must be evaluated.
fvec
Type: array<System..::..Double>[]()[][]
On exit: the function values fix (unless iflag is set to a negative value by fcn).
iflag
Type: System..::..Int32%
On entry: iflag>0.
On exit: in general, iflag should not be reset by fcn. If, however, you wish to terminate execution (perhaps because some illegal point x has been reached), then iflag should be set to a negative integer.
