BUG: 't_span' is illustrated as 2-tuple of floats in scipy‘s documention, but which is always defined as array_like in examples

Describe your issue.

https://docs.scipy.org/doc/scipy/reference/generated/scipy.integrate.solve_ivp.html#scipy.integrate.solve_ivp

We can notice that ‘t_span’ is illustrated as 2-tuple of floats in scipy‘s documention.

t_span: 2-tuple of floats Interval of integration (t0, tf). The solver starts with t=t0 and integrates until it reaches t=tf.

Then, the example is show below.

from scipy.integrate import solve_ivp

def exponential_decay(t, y): return -0.5 * y

sol = solve_ivp(exponential_decay, [0, 10], [2, 4, 8])

print(sol.t)

However, in third line of the above paragraph ,we use [0, 10] as ‘t_sapn’, which is array_like.

Reproducing Code Example

from scipy.integrate import solve_ivp
def exponential_decay(t, y): return -0.5 * y
sol = solve_ivp(exponential_decay, [0, 10], [2, 4, 8])
print(sol.t)

Error message

Firstly thanks to your reply.

In fact, I don’t know anything about document modification on the web, and I’m afraid I can’t complete a PR. I am sorry.

Sure, Thanks!
