__construct(callable $fun, bool $complex = false)

f receives/returns complex components encoded as [re, im] pairs (see integrate()).

complexOde(callable $fun): self

scipy.integrate.complex_ode(f): construct a complex-valued stepper.

setIntegrator(string $name, float $rtol = 1.0E-6, float $atol = 1.0E-12): self

scipy ode.set_integrator(name, **opts). Recognised names: 'dopri5' (-> RK45), 'dop853' (-> DOP853), 'vode'/'lsoda' (-> BDF). Options 'rtol' and 'atol' are honoured; others are accepted and ignored.

setInitialValue(array|float $y, float $t = 0.0): self

scipy ode.set_initial_value(y, t). For real mode $y is a list<float> (or scalar). For complex mode $y is a list of [re, im] pairs (or a single [re, im]); it is flattened to the internal real state.

setFParams(mixed ...$args): self

scipy ode.set_f_params(*args): extra positional args passed to f after (t, y).

integrate(float $t): array

scipy ode.integrate(t): advance the solution from the current time to $t and return y(t).

successful(): bool

scipy ode.successful(): whether the last integrate() step completed without error.

t(): float

Current integration time.

y(): array

Current solution value (same encoding integrate() returns).
