Real calcDerivative	(	const std::vector< int > &	derivComponents,
		const Vector &	x
	)			const `[inline, virtual]`

Calculate a partial derivative of this function at a particular point.

Which derivative to take is specified by listing the input components with which to take it. For example, if derivComponents=={0}, that indicates a first derivative with respective to component 0. If derivComponents=={0, 0, 0}, that indicates a third derivative with respective to component 0. If derivComponents=={4, 7}, that indicates a partial second derivative with respect to components 4 and 7.

Parameters:

	derivComponents	the input components with respect to which the derivative should be taken. Its size must be less than or equal to the value returned by getMaxDerivativeOrder().
	x	the Vector of input arguments. Its size must equal the value returned by getArgumentSize().

Implements Function_< T >.
