Member Function Documentation

template<typename T >

void roboptim::Cos< T >::impl_compute	(	result_ref	result,
		const_argument_ref	argument
	)		const

inlineprotectedvirtual

Function evaluation.

Evaluate the function, has to be implemented in concrete classes.

Warning: Do not call this function directly, call operator()(result_ref, const_argument_ref) const instead.

Parameters

result	result will be stored in this vector
argument	point at which the function will be evaluated

Implements roboptim::GenericFunction< T >.

template<>

void roboptim::Cos< EigenMatrixSparse >::impl_gradient	(	gradient_ref	gradient,
		const_argument_ref	argument,
		size_type	functionId
	)		const

inlineprotectedvirtual

Gradient evaluation.

Compute the gradient, has to be implemented in concrete classes. The gradient is computed for a specific sub-function whose id is passed through the functionId argument.

Warning: Do not call this function directly, call gradient instead.

Parameters

gradient	gradient will be stored in this vector
argument	point where the gradient will be computed
functionId	evaluated function id in the split representation

Implements roboptim::GenericDifferentiableFunction< T >.

template<>

void roboptim::Cos< EigenMatrixSparse >::impl_hessian	(	hessian_ref	hessian,
		const_argument_ref	argument,
		size_type	functionId
	)		const

inlineprotectedvirtual

Hessian evaluation.

Compute the hessian, has to be implemented in concrete classes. The hessian is computed for a specific sub-function which id is passed through the functionId argument.

Warning: Do not call this function directly, call hessian instead.

Parameters

hessian	hessian will be stored here
argument	point where the hessian will be computed
functionId	evaluated function id in the split representation

Implements roboptim::GenericTwiceDifferentiableFunction< T >.

template<>

void roboptim::Cos< EigenMatrixSparse >::impl_jacobian	(	jacobian_ref	jacobian,
		const_argument_ref	arg
	)		const

inlineprotectedvirtual

Jacobian evaluation.

Computes the jacobian, can be overridden by concrete classes. The default behavior is to compute the jacobian from the gradient.

Warning: Do not call this function directly, call jacobian instead.

Parameters

jacobian	jacobian will be store in this argument
arg	point where the jacobian will be computed

Reimplemented from roboptim::GenericDifferentiableFunction< T >.

template<typename T >

virtual std::ostream& roboptim::Cos< T >::print ( std::ostream & o ) const

inlinevirtual

Display the function on the specified output stream.

Parameters

o	output stream used for display

Returns: output stream
