- class ForwardEulerSolver(function, t0, y0, t_bound, vectorized=False, support_complex=False, num_t_steps=15)#
Forward Euler ODE solver.
Forward Euler ODE solver that implements an interface from SciPy.
function (Callable) – Right-hand side of the system. The calling signature is
fun(t, y). Here
tis a scalar, and there are two options for the ndarray
y: It can either have shape (n,); then
funmust return array_like with shape (n,). Alternatively it can have shape (n, k); then
funmust return an array_like with shape (n, k), i.e., each column corresponds to a single column in
y. The choice between the two options is determined by vectorized argument (see below). The vectorized implementation allows a faster approximation of the Jacobian by finite differences (required for this solver).
t0 (float) – Initial time.
y0 (Sequence) – Initial state.
t_bound (float) – Boundary time - the integration won’t continue beyond it. It also determines the direction of the integration.
vectorized (bool) – Whether
funis implemented in a vectorized fashion. Default is False.
support_complex (bool) – Whether integration in a complex domain should be supported. Generally determined by a derived solver class capabilities. Default is False.
num_t_steps (int) – Number of time steps for the forward Euler method.
