[Octave-bug-tracker] [bug #46247] [control] lsim() function - potential numerical problem ; various other edits

[Carnë Draug]

Follow-up Comment #1, bug #46247 (project octave):

I am unsure what happened, but the original got lost (probably due to the
sensitivity of savannahs markup).

Here is is again (it reads fine in the emails):

> The internal reconstruction of the time vector with  dt = t(2) - t(1);  and 
t = reshape (tinitial : dt : tfinal, [], 1);  can be susceptible to round-off,
rising unjustified complaints about size inconsistencies between U and T. The
attempted fix gives prime importance to the len_t  variable, instead of  dt.
On the fly, some other cosmetics are suggested, also in the help text.
