Maple Student Edition will support a co-processor if you have
one.  The slight degredation in speed is a side-effect of a more 
space efficient way of storing the library routines.   The routines
are "packed" to take up less space - "unpacking" them when they are
first loaded slows down the system marginally.

I saw the FAQ (Available Systems) here a while ago but the article had expired.
I've been waiting patiently ever since but it doesn't seem to have re-appeared.
Could anyone either email me or repost. Basically I'm after a free (if it
exists) PC or Mac symbolic/calculus/graphing application. Something with the
capabilities of Mathematica or Maple would be just fine.

P.S. Please don't suggest the Student versions of either Mathematica ($AUS 350)
     or Maple (I've never seen it advertised by anyone here).

I'm using Mathematica to generate some Fortran code.  The 22
expressions currently turn into about 256 lines of code (the longest
expression is about 34 lines long) without use of Simplify or Factor.
Applying Simplify to the expressions takes a long time (2638 minutes
so far on an IBM RS/6000 with only 1 of the 22 finished), though it
does shorten the code (down to 7 lines from 26 on the only expression
that has been completed so far).  Does anybody know of a better way of
simplifying expressions?  Has anybody written a package to optimize
the fortran code that it output?  Has anybody written a module that
generates CM fortran code in terms of the shift calls?

I am a junior student at Western Michigan University.
I want to learn the software Mathematica which is installed on

Can anyone kindly recommend me some very basic and simple book

   Subject: dumb maple question -- differential equations

   ...   (header and sample session deleted)

   There are several things I'd like to do with this data which 
   I haven't had much luck with:

   1)  I'd like to break v1(t), v2(t), pr(t) into separate functions.  While
   this sounds trivial, the only way I've been able to do it is with 

   V1 proc(t) op(2,op(2,pv(t))) end;

   which looks fairly inelegant.

Unfortunately, because Maple's sets are unordered, the hardcoded "2" in
the first op call above will cause problems.  A more robust, but uglier,
version is:
V1 := proc(p)
        local i,v;
           v := pv(p);
           for i in v do
              if op(1,i) = 'v1(t)' then RETURN(op(2,i)) fi
           od;
           ERROR(`Could not find v1`);
      end;

   2)  I'd like to collect a large (say 10000 point) array of data from each
   of the functions.  Any attempt at this has taken what seems to be
   an unbearably long time.  I've been using a do loop and putting data
   in each array bucket.

Generating 10000 points from dsolve will take a long time.  We are working
on speeding this up.  The only suggestion I can make is to generate the 
points in order so that no unnecessarily large changes occur in the parameter
value.

   3) I'd like to plot these derived function.  In the V1 I defined above, 
   I get the following errors:

   > plot(V1,0..10);
   Error, (in f) wrong number (or type) of parameters in function type;

I could not actually duplicate this error, but because of the set ordering
problem I mention above the resulting plot was not useful.  There is a 
command odeplot in the plots package for plotting the output of dsolve.

   help??

I don't think so. Because I answered the question about SIMTEL20 software
posted by Li and SymbMath is not commerical. Everyone can get it free from
SIMTEL20. If you like to wonder if something constitutes commerical use of

	You'll want to have access to Wolfram's "Mathematica" though the
book is porely written.  I think there's a book called mathmatica made
easy or something like that which is a good beginer book.  Tell your
local computer or book store to look up Mathematica in the INGRAM catalog. 
Another good book is Maeder, "Programing in Mathematica".
