示例1: operator
void operator() (const state_type x, state_type& dxdt, double t) {
// for input voltage, model a step function at time zero
double Va = 0;
if (t > 0.0) {
Va = vin_;
}
Matrix<double, 1, 1> u; u << Va;
// All other node voltages are determined by odeint through our equations:
Map<const Matrix<double, 2, 1> > xvec(x.data());
Map<Matrix<double, 2, 1> > result(dxdt.data());
result = coeff_ * xvec + input_ * u;
}示例2: result
// utility function for displaying data. Applies internal matrices to state
std::vector<double> state2output(state_type const& x) {
std::vector<double> result(2);
Map<const Matrix<double, states, 1> > xvec(x.data());
Map<Matrix<double, 3, 1> > ovec(result.data());
ovec = Lred_.transpose() * xvec; // in theory the input could be involved via Dred_
return result;
}示例3: operator
void operator() (const state_type x, state_type& dxdt, double t) {

if (agg_slew_ == 0) {

} else {
// find the "real" ramp starting point, since we use the center of the swing

double real_start = agg_start_ - transition_time;

} else if (t <= real_start) {
Vagg = (agg_slew_ > 0) ? 0 : v_; // remain at initial value
} else {

}
}
// same for the victim driver
