MinConNLPIGradientGradient Method |
Computes the value of the gradient of the function at the given
point.
Namespace: Imsl.MathAssembly: ImslCS (in ImslCS.dll) Version: 6.5.2.0
Syntax void Gradient(
double[] x,
int iact,
double[] result
)
Sub Gradient (
x As Double(),
iact As Integer,
result As Double()
)
void Gradient(
array<double>^ x,
int iact,
array<double>^ result
)
abstract Gradient :
x : float[] *
iact : int *
result : float[] -> unit
Parameters
- x
- Type: SystemDouble
An input double array, the point at which the gradient
of the objective function or gradient of a constraint is to be
evaluated.
- iact
- Type: SystemInt32
An input int value indicating whether evaluation of the
objective function gradient is requested or evaluation of a
constraint gradient is requested. If iact is zero, then an
objective function gradient evaluation is requested. If iact is
nonzero then the value of iact indicates the index of the
constraint gradient to evaluate. (1 indicates the first
constraint, 2 indicates the second, etc.)
- result
- Type: SystemDouble
A double array. If iact is zero, then the value of the
objective function gradient at x is returned in result. If iact
is nonzero, then the computed gradient of the requested
constraint value at the point x is returned in result.
