Method Detail

calculatePartialDerivative

double calculatePartialDerivative(int reaction,
                                  AmountManager amount,
                                  int reactantIndex,
                                  double volume)

Calculates partial differentials of the propensity functions for the tau leaping methods. If a positive value for volume is given, it is assumed that the constants are deterministic rate constants and are hence transformed to specific reaction rate constants.

Parameters:

reaction - the reaction index

amount - the AmountManager

reactantIndex - the network index of the reactant to calculate the partial differential for

volume - the volume of the reaction space

Returns:

partial differential
