I'm applying laplace transform to a spring-mass system, the most basic one. I write this code which takes initial values x(0) and v(0) as input and I'm computing x(t) in matlab. But for some values it gives me complex roots for x(t) which doesn't seem possible. If not for laplace I can solve the same question traditional differential equation solving way and get real roots. So what's happening here?(adsbygoogle = window.adsbygoogle || []).push({});
