void FitzHughNagumo1961OdeSystem::EvaluateYDerivatives	(	double	time,
		const std::vector< double > &	rY,
		std::vector< double > &	rDY
	)			[virtual]

Compute the RHS of the FitHugh-Nagumo system of ODEs

Parameters:

	time	the current time, in milliseconds
	rY	current values of the state variables
	rDY	to be filled in with derivatives

Implements AbstractOdeSystem.

double FitzHughNagumo1961OdeSystem::GetIIonic

(

const std::vector< double > *

pStateVariables = NULL

)

[virtual]

Calculates the ionic current.

Parameters:

pStateVariables

optionally can be supplied to evaluate the ionic current at the given state; by default the cell's internal state will be used.

Returns:

the total ionic current

Implements AbstractCardiacCellInterface.
