void LuoRudyIModel1991OdeSystem::VerifyStateVariables

(

)

[private, virtual]

Range-checking on the current values of the state variables. Make sure all gating variables have are within zero and one, and all concentrations are positive

Reimplemented from AbstractCardiacCell.

Definition at line 257 of file LuoRudyIModel1991OdeSystem.cpp.

References AbstractOdeSystem::DumpState().

void LuoRudyIModel1991OdeSystem::EvaluateYDerivatives	(	double	time,
		const std::vector< double > &	rY,
		std::vector< double > &	rDY
	)			[virtual]

Fill in a vector representing the RHS of the LuoRudyIModel1991OdeSystem system of Odes at each time step, y' = [y1' ... yn']. Some ODE solver will call this function repeatedly to solve for y = [y1 ... yn].

Parameters:

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

Implements AbstractOdeSystem.

double LuoRudyIModel1991OdeSystem::GetIIonic

(

)

[virtual]

Computes the total current flowing through the cell membrane, using the current values of the state variables.

Implements AbstractCardiacCell.

Definition at line 201 of file LuoRudyIModel1991OdeSystem.cpp.

References fast_sodium_current_E_Na.

double LuoRudyIModel1991OdeSystem::GetIntracellularCalciumConcentration

(

)

[virtual]

[Ca_i] is needed for mechanics, so we explcitly have a Get method (rather than use a get by name type method, to avoid inefficiency when using different cells types of cells). This method by defaults throws an exception, so should be implemented in the concrete class if IntracellularCalciumConcentration is one of the state variables

Reimplemented from AbstractCardiacCell.
