Description
Let say I have a function $h(t)$ that I can evaluate in any $t$ and I want to calculate $$\int_0^1 h(t) dt.$$
Would diffrax used like that be a good idea?
def h(t):
return t**2
dx.diffeqsolve(
dx.ODETerm(lambda t, _y, _args: h(t)),
dx.Tsit5(),
0.0,
1.0,
dt0=None,
y0=0.0,
stepsize_controller=dx.PIDController(rtol=0.0, atol=1e-3),
).ys.squeeze(0)
