What is the MATLAB Internal Architecture?

SmartEngineer — Sat, 06 Oct 2007 07:44:35 -0400

Hello,
Can anyone explain the internal arcitecture of the
MATLAB.How it is actually working in some detail.

Thank you.

You type in an expression, it parses it and then if no error in syntax
is found, computes a result...

As Dr Lara asks, what precisely, do you propose to do with this
information? :)

Hello,
      TO start with thanks for your attention.

   I was asking for the execution of the codeThis is
something anybody can tell I need not come to the MATLAB
forum to get such a response.

    Well you can tell Dr.Lara that we are here to discuss
and gain knowledge here and implement things better using
MATLAB with a better understanding of the underlying
concepts.

You can get some insight from this article:

Sorry you didn't seem to relate to the technique; I was trying to elicit
some input on what, more specifically, you had in mind that knowing
something about the internals of Matlab would help you implement.

The question as posed is so generic there's no practical way to respond
imo. The overall idea of efficiency in using Matlab is to try to find
ways to express your problem such that you can take as much advantage of
the vectorizing capabilities as possible. There are several articles in
the documentation that discuss efficiency and things to avoid to
minimize overhead. The external API section discusses the internal data
object of the array.

Once you get through that, the best way to approach Matlab programming
probably is then to simply implement whatever your problem is in as a
most straightforward way you can and only if that shows up a performance
problem to worry about it -- the prime advantage of Matlab is in being
able to prototype in a quick manner as compared to a lower level
language. If one gets bogged down in the optimization question too
early, much time may be spent on details that don't, in the end, turn
out to make any significant difference globally although they might make
measurable improvements locally. This is really only a rehash of the
well-known mantra of don't try to optimize without first profiling.

Hi,

The link seems to have been broken apart by the newsreader. Try

Hey dude,

there are some issues with your postings:

* Apparently, you have no real name. Are you too shy?
* From your pseudonym "SmartEngineer" I got high expectations. However,
you don't even manage to open a link containing a line break. That's
embarrassing!

Cheers,

Hello Armin,
           Well ...I guess we are here to discuss about
MATLAB and not about me or you ..ok.As long we discuss
something useful and relevant in this Forum...I guess we
it will be beneficial to all of us.
          If have any thing to discuss with me ..you can
mail me..Mathworks has provided you that option.
          Regarding your second point...well Nobody is a
perfect human...and yea it was embarasing...However when
you are willing to learn these things happen and we should
try to improve by looking the bigger picture(..I thank
those guys who corrcted me immediately ..Infact I received
3 messages correcting me.)...rather than just
flourishing ..irrelevant and time wasting comments....If
you have some thing to add to the thread topic I welcome
you we can discuss..but dont waste your time ...with such
silly notes.

Regards
