)
virtual
double OpenSim::PiecewiseConstantFunction::calcDerivative ( const std::vector< int > &  derivComponents,
const SimTK::Vector &  x 
) const
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
derivComponentsthe 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().
xthe Vector of input arguments. Its size must equal the value returned by getArgumentSize().

Reimplemented from OpenSim::Function.
