Please tell me if the system with following open loop transfer function is stable? Marginally stable? Or unstable?
<b>H(s) = 1/(s*(s+2))</b>
I think the system is marginally stable because of the pole at origin. But when I plot the step response in MATLAB I get a linear line which keeps on increasing that makes me think that system is unstable. Link for step response is given below:

Any help would be appreciated.
