I need some hep with this last step.
I am following a guide to try and info out of a laplace transform.
This is the code I have, and my attempt to get the highlighted solution.
This has everything I need I am just not sure how to get the final output. For example I don't know how MATLAB will always order the values. Like if -0.25 should be assigned to s or s^2.

I don’t recognise ‘poly2str’ and the only MATLAB function I can find that would be similar is poly2sym.
Taking a shortcut, try this —
syms F(s) s t
F(s) = (s^2+1) / (s^2*(s+2))
F = partfrac(F)
f(t) = ilaplace(F)
f = vpa(f, 3)
.
