Member Function Documentation

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.
