Yes it is possible.  There are many ways to do it. One is to use telnet. 
There is
even a server at www.franz.com.

Presumably you already know about the existing graphical front ends.  If
not, I suggest you learn about them, e.g. texmacs, emaxima, xmaxima, 
wmaxima, imaxima
and a few others. If you don't have any new ideas  (oh, running over a 
network
is not new.) then maybe you should consider as an alternative, refining one 
of the existing
projects, or picking up something that is on someone's "to do" list for 
Maxima.

Hello Jo,

> I am wondering how to compute calculations over

There are various user interfaces for Maxima.
Some are listed here: http://maxima.sourceforge.net/relatedprojects.shtml
In particular http://www.et.byu.edu/~koj/maxima.html
seems work pretty well.

So far as I know, all existing graphical interfaces talk to
a separately-running Maxima session via a socket.
It is probably possible to put the Maxima session and
the graphical interface on separate machines, although
I don't know the details about that.

If you would like to work on a graphical interface,
I'll bet the WxMaxima project (link on the "related projects"
page cited above) can use some help.

Thanks for your interest in Maxima,

Robert Dodier

only???

Thanks

Maxima i18n and Windows builds

Hi!

I'd like to report that Maxima i18 framework
for describe and HTML documentation is mostly
finished:

(1) Building of Spanish and Portuguese documentation
is activated by configure options --enable-lang-es and
--enable-lang-pt.

(2) On Windows and as rpm Spanish and Portuguese
documentation (.info and .html) is packaged as additional
language packs.  These .info and .html documentation are
installed into /es and /pt subdirectories of standard
.info and .html installation directories (here English
documentation resides).

(3) Maxima automatically set *maxima-lang-subdir* to
"es" or "pt" using current user's locale (environment
variable MAXIMA_LANG_SUBDIR overrides it).  And if
*maxima-lang-subdir* is not nil then describe first
tries to find documentation in this subdirectory
and only if no docs found here tries standard English
.info.   Analogously xmaxima menu item "Maxima Help"
shows Spanish or Portuguese .html depending on
current locale setting.

Known problems:

(a) Command line Maxima is not locale-aware.

Installation on WinXP


Greetings!

I'm trying to install Maxima on my Windows XP machine at home.  I 
downloaded and installed the 5.9.2 and have since downloaded Clisp and 
extracted it.  But things aren't marrying-up properly.  Maxima is not 
starting when I open up the program.  I'm either missing a dependency, too 
ignorant to attempt implementing maxima on my own, or both.

Any simple installation help out there?  From what I'm reading on this 
list, this project is mostly by folks a lot more savvy than I am, and who 
leave things unsaid that the likes of this writer need to see in triplicate.

I used macsyma years ago on a SUN 3/60 machine, and I'm excited to hear 
about an open-source CAS, but I may not have the requisite background to 
implement it myself.

I've looked for all kinds of "installation for dummies" documentation and 
have failed to find the needed detail.  Any help would be appreciated.

Thanks,

Steve

Unless you want to build Maxima from source, you don't need to
install Common Lisp. Did you use the self-contained maxima-5.9.2.exe
from

http://sourceforge.net/project/showfiles.php?group_id=4933

or did you download something else? We've had reports
that some firewalls interfere with running Maxima
under windows. Might that be the problem?

Re: rational numbers only

Don't put any floating point numbers into maxima.  Use 1/2   not 0.5

Or you can use the program  rat(......)
to convert to rational approximations, in some contexts.

If you downloaded the windows executable, you are done.

The windows executable does not
need Clisp and in fact, does not even use it, but another implementation
of lisp, GCL.

  But things aren't marrying-up properly.  Maxima is not

which program? did you click on the maxima icon?

Maxima Install


Hi Barton,

To fill in some more detail:

When I first executed the program, I got a warning from Norton Anti-Virus, 
and (too-) hastily followed its "Block all ... from/to this ..." 
recommendation.  Following your previous, I'm now in Norton, seeing if I 
can pinpoint the issue.

Thx,

Steve

Re: rational numbers only

Hi Richard and Stravos.

My original idea was avoid manual convertion like 0.5 to 1/2. But as this is 
not automatically make for maxima the original idea was changed:

Need a function that view an generic numerical expression of any lenght like:

0.5 + 1/3 - 3/8 +0.3*1/4

detect the decimal number, convert it for rational number, show the convertion 
of this decimal to rational and show the result in a rational number.

This is for teaching childrens to calculate the numérical expressions and 
return its value in a simplificated form.

Thanks.
