Function Documentation

static int f (  realtype  t,
N_Vector  y,
N_Vector  ydot,
void *  f_data
)  [static]
 

Wrap function for solver f for computing of $ f $ in $ \frac{\partial\vec{q}}{\partial t}=f(\vec{q}, \vec{Q}, \vec{p}) $.

This function makes the bridge between the Sundials ODE-solver and the evaluation function compute_state_dot()

Parameters:
t : time
y : state ($ \vec{q} $) in the datatype needed by the solver
ydot : evaluation output ($ \frac{\partial\vec{q}}{\partial t} $)
*f_data,: pointer of type void, pointing on the ODE_data type struct containing all the model's data
Returns:
: 0 (no meaning yet <=> no integration error handling yet!!!)
