Copy

public virtual void Gradient(
	DoubleVector x,
	DoubleVector grad
)

Public Overridable Sub Gradient ( 
	x As DoubleVector,
	grad As DoubleVector
)

public:
virtual void Gradient(
	DoubleVector^ x, 
	DoubleVector^ grad
)

abstract Gradient : 
        x : DoubleVector * 
        grad : DoubleVector -> unit 
override Gradient : 
        x : DoubleVector * 
        grad : DoubleVector -> unit

Parameters

x DoubleVector: The point at which to evaluate the gradient.
grad DoubleVector: The vector into which to place the gradient.

Exceptions

Exception	Condition
InvalidArgumentException	Thrown if the gradient or x vector does not have length equal to the dimension of the domain of the functional.
