I am wondering how to export MATLAB function ode45 to python. According to the documentation is should be as follows: MATLAB: [t,y]=ode45(@vdp1,[0 20],[2 0])

Solving coupled differential equations with sympy

I am trying to solve the following system of first order coupled differential equations: - dR/dt=k2*Y(t)-k1*R(t)*L(t)+k4*X(t)-k3*R(t)*I(t) - dL/dt=k2*Y(t)-k1*
