comment timing series algorithm
I think you got the wrong group? May be you wanted math.stackexchange.com but you can try floor(T/delT)+1, where delT is timing between events. Assumed the same for all. Assuming event numbered 1, starts at t=0.

comment Where can I learn to use mathematica comprehensively?
comprehensive way to learn the entire system I believe this is impossible to do. Mathematica is too large and complicated to be learned fully and comprehensively in one life time by any one. You could learn parts of it well may be, but not the whole system. I do not think there any one person living who have used all of Mathematica commands for example. (well, may be MrWizard did) but I mean for the rest of us, this is impossible task.

You can use ListLinePlot on your (t,x) data.

comment Why does LyapunovSolve solve non-standard form?
Ican't tell now, but just to note that Matlab also solves the same form as Mathematica: mathworks.com/help/control/ref/lyap.html.

whereas the standard form of the Lyapunov function When one says the standard is this and that, it will nice to show a link?

comment Better Autocompelete for the Front-End
Since version 9, autocomplete behaves the way it does in modern IDEs except for one big shortcoming how-to-keep-the-ctrlshiftk-help-menu-remain-in-display-while-typing (and there is no answer to this as of version 10.01)

comment How does Mathematica integrate?
For example it fails on Integrate[x^3 ExpIntegralE[1, x], x] as of version 10.01, M can now solve this and gives this: -x^3 ExpIntegralE[2, x] - 3 (x^2 ExpIntegralE[3, x] + 2 (x ExpIntegralE[4, x] + ExpIntegralE[5, x])) which is the same as the expression you show. (after some simplifications)

comment Catastrophic loss of precision
Please change the letter l to something else, say L0. I can figure if I am looking at a 1 or l in your code, they look very much the same.

it says to find the derivative derivative with respect to what? when taking derivative it has to be with respect to something.

comment How to extract a list of available Method-s
@AlexeiBoulbitch I've added another function to filter only those options which has the Method-> on them and only show those. I kept the original function as is.
