NumericalDerivativesIFunctionF Method |
Returns the equations evaluated at the point
y. If
the user does not override the
EvaluateF method,
then
F is also used to compute the function values
at the current independent variable values
.
Namespace: Imsl.MathAssembly: ImslCS (in ImslCS.dll) Version: 6.5.2.0
Syntax double[] F(
int varIndex,
double[] y
)
Function F (
varIndex As Integer,
y As Double()
) As Double()
array<double>^ F(
int varIndex,
array<double>^ y
)
abstract F :
varIndex : int *
y : float[] -> float[]
Parameters
- varIndex
- Type: SystemInt32
An int indicating the index of the variable to perturb.
varIndex = 1 indicates variable 1 in y[0].
- y
- Type: SystemDouble
A double array of length n, the point at which
the Jacobian is to be evaluated.
Return Value
Type:
Double
A
double array of length
m. The equations
evaluated at the point
y.
