WebSystems of ODE Solving a system of ODE in MATLAB is quite similar to solving a single equation, though since a system of equations cannot be defined as an inline function, we must define it as an M-file. Example 2. Solve the Lotka–Volterra predator–prey system dy1 dt =ay1 −by1y2; y1(0) = y 0 1 dy2 dt = − ry2 +cy1y2; y2(0) = y 0 2,
