如何用两个微分方程显示曲线？

Question

Hello i'm trying to implement the euler explicit method with my code. Here are my two differential equation. - dSdt = ps S (1-((R + S)/K)) - (C * S) - dRdt = pr R (1-((R + S)/K)) - (beta S R)

How can i display the curve ?

Thank you for your answers.

h = 0.5
t = np.linspace(0, 35, 35)
def S(t):
    if(t <= 0):
        return S0
    else:
        return funcS(t - h) + h * ps*funcS(t - h)*(1-((funcR(t - h) + funcS(t - h))/K)) - (C * funcS(t - h))

def R(t):
    if(t == 0):
        return R0
    else:
        return pr*funcR(t - h)*(1-((funcR(t - h) + funcS(t - h))/K)) - (beta*funcS(t - h)*funcR(t - h))

Try this with matplotlib:

import matplotlib.pyplot as plt

plt.plot(t, S(t))          # assuming you want to plot S(t)
plt.show()                 # this will display your figure
