MatrixIntegrator(const DynamicalSystem &ds, const NonSmoothDynamicalSystem &nsds, const TimeDiscretisation &td)

Constructor to compute \(\int exp(A\tau)\mathrm{d}\tau\).

Parameters:

• ds – the DynamicalSystem

void integrate()

Computes the next value of _mat.

inline const SiconosMatrix &mat() const

Get the value of _mat, solution of the ODE.

Returns:

a reference to _mat

inline bool isConst()

Check whether the solution of the ODE is time-invariant.
