}Expand description
Courbage-Nekorkin-Vdovin (2007) discontinuous two-dimensional spiking map.
Canonical map (Chaos 17:043109; arXiv:0712.2097, eqs. 3-5):
x(n+1) = x(n) + F(x(n)) - y(n) - beta*H(x(n) - d) + I
y(n+1) = y(n) + eps*(x(n) - J)
F(x) = -m0*x for x <= Jmin
m1*(x - a) for Jmin < x < Jmax
-m0*(x - 1) for x >= Jmax
H(z) = 1 for z >= 0, else 0
Jmin = a*m1/(m0 + m1), Jmax = (m0 + a*m1)/(m0 + m1)Defaults place the model in the published chaotic spiking-bursting regime.
The arithmetic is exact (no transcendental functions), so simulate is
bit-identical to the Python NumPy reference and the Julia/Go backends.

impl CourageNekorkinMapNeuron
pub fn new() -> Self
pub fn step(&mut self, current: f64) -> i32
Sourcepub fn simulate(&mut self, n_steps: usize, current: f64) -> (Vec<f64>, i64)
pub fn simulate(&mut self, n_steps: usize, current: f64) -> (Vec<f64>, i64)
Run n_steps under a constant input, returning the x trace and the
upward-crossing spike count. Reuses step so the trace is bit-identical
to the per-step path and to the Python reference. The final state is left
in self.x / self.y.
