Method Details

dim

public int dim()

Description copied from interface: VectorDifferentiableFunction

Returns the dimensionality of the function domain. If dim() returns (n) then this function expects an n-vector as its input.

Specified by:

dim in interface VectorDifferentiableFunction

Returns:

the expected dimension of the function's domain

value

public RealVector value(RealVector x)

Description copied from interface: VectorDifferentiableFunction

Returns the value of this function at (x)

Specified by:

value in interface VectorDifferentiableFunction

Parameters:

x - a point to evaluate this function at.

Returns:

the value of this function at (x)

jacobian

public RealMatrix jacobian(RealVector x)

Description copied from interface: VectorDifferentiableFunction

Returns the gradient of this function at (x)

Specified by:

jacobian in interface VectorDifferentiableFunction

Parameters:

x - a point to evaluate this gradient at

Returns:

the gradient of this function at (x)
