Before explaining it is necessary to implement working
Maxima + other lisps on Windows,  package it in some
kind of Windows installer etc.

This is not true.

Presently situation with Windows installation is:

1. You can not build Maxima CVS since automake
doesn't work with ActivePerl.

2. You can build Maxima from the distribution tarball
and this doesn't require Perl since all .html, .info
are present in the tarball.

This is true for the forthcoming Maxima 5.12 and Perl
out of the game here (any version).

For Maxima 5.11 you do need ActivePerl 5.8 but you
still can not build Maxima using CVS.

For Maxima 5.10 and below you can do anything
and Perl 5.6 which comes mingw is enough.

I don't understand this kind of argumentation.

You mean people with LISP only will build Maxima using INSTALL.lisp
instructions?
Perfect, (its the way I do), they could download HTMLs or PDFs from the
main web site.
There are many distros (e.g. ActiveTcl) where you can download HTML
separatedly.

On the other side, the current way of packing source tarball is okay for
me, it just seems unnatural.
(what if user do not have TAR program?)

Re: A partfrac limitation

You can help partfrac by factoring the denominator. In cvs maxima:

load(simplify_sum)$
my_partfrac(e, x) := partfrac(num(e)/factor_with_solve(e, x), x)$
my_partfrac(1/(x^4+20*x^2+120), x);

will compute the partial fraction representation.

Not all Unix systems have Perl.
Not all Unix systems have Perl 5.8.
Not all Unix systems have appropriate makeinfo.

autoloading functions from linearalgebra

Hi Barton,

I tried to add autoload properties to all Maxima-level functions 
from linearalgebra. 
There occurs a problem with a global variable named $generalring:

(%i1) M : matrix ([1 - z, 3], [3, 8 - z])$
(%i2) lu_factor (M, generalring);
                             [ 1 - z    3   ]
(%o2)              lu_factor([              ], generalring)
                             [   3    8 - z ]
(%i3) load("E:\\home\\maxima\\autoload\\max_ext.lisp");
(%o3)          E:\home\maxima\autoload\max_ext.lisp
(%i4) lu_factor (M, generalring);
                [ 1 - z         3        ]
                [                        ]
(%o4)          [[   3            9       ], [1, 2], generalring]
                [ -----  - z - ----- + 8 ]
                [ 1 - z        1 - z     ]

So $lu_factor is autoloaded here, but $generalring isn't, which is 
in mring.lisp. 

For the same reason the corresponding example from the documentation 
doesn't work. 

What do you suggest me to do?

Best

Problem with linsolve?

Hi,

I'm having the following problem with linsolve:

X : genmatrix(x,3,3)$
r(i) := sum(X[i,j],j,1,3)
linsolve([r(1)=10,r(2)=5], [X[1,1],X[1,2]])

Maxima encountered a Lisp error:
Error during processing of --eval option "(cl-user::run)":
The value 2 is not of type LIST.
Automatically continuing.
To reenable the Lisp debugger set *debugger-hook* to nil.

If I remove r(2)=5 from the list of equations, the error goes away.
Does anyone have an idea about what is going on?

Re: autoloading functions from linearalgebra

I don't know. Try the same experiment, but do trace(load) first.
If I knew the relevant lines from max_ext.lisp (is it in
CVS ?), it might help me find a solution.

The Maxima source code is bundled with the binary installation
files (rpms for Linux, installer .exe for Windows, dunno about other
platforms). You can also get the source code alone.
For all of the above, see the Sourceforge download page.
http://sourceforge.net/projects/maxima then follow the link to
"Files" or "Download" (I forget what it says exactly).

The Maxima project is still active. See http://maxima.sourceforge.net
for more about the history of the project.

Hope this helps

No, it has not.

Yes, go to http://maxima.sourceforge.net/ and follow the links.
