Translation please

[edit]

Can someone please translate this article into terms which a non-mathematician would understand? - An Australian engineer too lazy to log in —Preceding unsigned comment added by 202.147.46.214 (talk) 00:42, 20 February 2008 (UTC)[reply]


My big concern, AS a mathematician, is that as near as I can tell this article is factually inaccurate. A linear dynamical system, at least as I learned the term, is deterministic not probabilistic. The intro of this article states that a linear dynamical system is a bayesian model, which is totally at odds with my understanding, but the rest of the article talks about the subject as I understand it with no mention of probability. I'm holding off on editing though on the chance that I'm completely off base here; bayesian statistics isn't really my area. —Preceding unsigned comment added by Fcady2007 (talkcontribs) 02:52, 12 May 2011 (UTC)[reply]

it may also be helpfull if there was an explination of the intergral of lamda[k]r[k] and why it results in an exponential function 62.189.19.125 (talk) 15:40, 21 December 2011 (UTC)[reply]


Being a mathematician and usually doing Bayesian modeling I'd say this article should be about deterministic systems with a mentioning of the probabilistic version. So I would define the term as you would. T3kcit (talk) 07:07, 19 May 2011 (UTC)[reply]

Maybe we should rename the voice

[edit]

I think it would be more appropriate to call this voice "Continuous linear dynamical system" because there are also "discrete linear dynamical system"s which are not considered here.--Pokipsy76 (talk) 13:45, 12 July 2010 (UTC)[reply]

Opening Sentence

[edit]

The opening sentence on this article is a painful tautology to read. Surely it can be improved.

"Linear dynamical systems are dynamical systems that are linear."

That has been fixed, but is it correct: should “whose evaluation functions are linear” perhaps read “whose evolution functions are linear” (though the link, being redirected to dynamical system is actually useless)? PJTraill (talk) 22:45, 28 July 2014 (UTC)[reply]

Evaluation functions

[edit]

the Evaluation functions wiki link is broken — Preceding unsigned comment added by 2A02:2149:8806:E400:49EF:8D6A:553D:F1A9 (talk) 23:31, 30 August 2018 (UTC)[reply]

The content should be improved with details and visualization

[edit]

As a classic theory, linear dynamics has been researched a lot with various rigorous results worth a textbook. But landing on this page, I'm very surprise to see the content is so simple... to the point that it seems unrecognizable visually!?!

At least, the classification should be enhanced with visualization like the following:

  • 2D: Instead of the text-only figure
    Current figure on the page
    , there should be sample vector fields attached like this.

Here are some codes (Chebfun2) to generate visuals: https://www.chebfun.org/examples/ode-linear/DynamicalSystems.html

  • 3D: Some animation with 3 complex eigenvalues like this:
