Hello, to solve a system of ODEs, I set up a Python-code with solve_ivp as ODE-solver. The solver is calling a function, which generates my ODE-system. Inside my ODE-system, I need the previous timesteps t(t-1) and solutions y(t-1), which were calculated by solve_ivp. Is there a way to get solutions and timesteps of previous calculations? Beste greetings! Mathias

# In Spyder, run the following short code.
from scipy.integrate import solve_ivp
def exponential_decay(t, y):
return - 0.5 * y
sol = solve_ivp(exponential_decay, [0, 10], [1])
print(sol.t)
print(sol.y)
print(sol.y.shape) # The array is 1 row and 8 columns.
print(sol.y[0, 6]) # Print the value in row 0, column 6. Remember Python is zero-based indexing!
