◆ impl_compute()

template<typename T>

void roboptim::Sin< 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 >.

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
