示例1: calculate
void SpathVessel::calculate( const unsigned& current, MultiValue& myvals, std::vector<double>& buffer, std::vector<unsigned>& der_index ) const {
double pp=mymap->getPropertyValue( current, getLabel() ), weight=myvals.get(0);
if( weight<getTolerance() ) return;
unsigned nderivatives=getFinalValue()->getNumberOfDerivatives();
buffer[bufstart] += weight*pp; buffer[bufstart+1+nderivatives] += weight;
if( getAction()->derivativesAreRequired() ) {
myvals.chainRule( 0, 0, 1, 0, pp, bufstart, buffer );
myvals.chainRule( 0, 1, 1, 0, 1.0, bufstart, buffer );
}
