The following is a collection of synonyms for various operations in
the computer algebra systems <FONT COLOR=purple>[Axiom]</FONT>, <FONT COLOR=purple>[Derive]</FONT>, <FONT COLOR=purple>[GAP]</FONT>, <FONT COLOR=purple>[Gmp]</FONT>, <FONT COLOR=purple>DoCon</FONT>,
<FONT COLOR=purple>[Macsyma]</FONT>, <FONT COLOR=purple>[Magnus]</FONT>, <FONT COLOR=purple>[Maxima]</FONT>, <FONT COLOR=purple>[Maple]</FONT>, <FONT COLOR=purple>[Mathematica]</FONT>, <FONT COLOR=purple>[MuPAD]</FONT>, <FONT COLOR=purple>[Octave]</FONT>,
<FONT COLOR=purple>[Pari]</FONT>, <FONT COLOR=purple>[Reduce]</FONT>, <FONT COLOR=purple>[Scilab]</FONT>, <FONT COLOR=purple>[Sumit]</FONT> and <FONT COLOR=purple>[Yacas]</FONT>. This collection does not
attempt to be comprehensive, but hopefully it will be useful in giving
an indication of how to translate between the syntaxes used by the
different systems in many common situations. Note that a blank entry
means either (a) that there may be an exact translation of a
particular operation for the indicated system, but we don't know what
it is or (b) there is no exact translation but it may still be
possible to work around this lack with a related functionality.<BR>
<BR>
While commercial systems are not provided on this CD the intent of the
Rosetta effort is to make it possible for experienced Computer Algebra
users to experiment with other systems. Thus the commands for
commercial systems are included to allow users of those systems to
translate.<BR>
<BR>
Some of these systems are special purpose and do not support a lot of
the functionality of the more general purpose systems. Where they do
support an interpreter the commands are provided.<BR>

Subject: Remarks concerning GAP
Message-ID: <20060523113926-0500@wiki.axiom-developer.org>

While the given GAP command does generate the list [1, 2, ..., n], the other examples seem to generate the list
[f(1), f(2), ..., f(n)].  This can be done with::

  List([1..n],f);

I'm not sure what Apply a fun. to a list of its args is supposed to mean, but my answer to that request is::

  CallFuncList(f,l);

A groebner basis can be computed with::

  GroebnerBasis([p1,p2,...],MonomialLexOrdering());

 1  Rosetta Translations

1.1  Introduction

The following is a collection of synonyms for various operations in the computer algebra systems [Axiom]?, [Derive]?, [GAP]?, [Gmp]?, DoCon?, [Macsyma]?, [Magnus]?, [Maxima]?, [Maple]?, [Mathematica]?, [MuPAD]?, [Octave]?, [Pari]?, [Reduce]?, [Scilab]?, [Sumit]? and [Yacas]?. This collection does not attempt to be comprehensive, but hopefully it will be useful in giving an indication of how to translate between the syntaxes used by the different systems in many common situations. Note that a blank entry means either (a) that there may be an exact translation of a particular operation for the indicated system, but we don't know what it is or (b) there is no exact translation but it may still be possible to work around this lack with a related functionality.

While commercial systems are not provided on this CD the intent of the Rosetta effort is to make it possible for experienced Computer Algebra users to experiment with other systems. Thus the commands for commercial systems are included to allow users of those systems to translate.

Some of these systems are special purpose and do not support a lot of the functionality of the more general purpose systems. Where they do support an interpreter the commands are provided.

Originally written by Michael Wester. Modified for Rosetta by Timothy Daly, Alexander Hulpke (GAP).

The following commands work only on expressions that consist of a single level (e.g., x + y + z but not a/b + c/d).

Remarks concerning GAP --Christian Sievers, Tue, 23 May 2006 11:39:26 -0500 reply
While the given GAP command does generate the list [1, 2, ..., n]?, the other examples seem to generate the list [f(1), f(2), ..., f(n)]?. This can be done with: 

  List([1..n],f);

I'm not sure what Apply a fun. to a list of its args is supposed to mean, but my answer to that request is: 

  CallFuncList(f,l);

A groebner basis can be computed with: 

  GroebnerBasis([p1,p2,...],MonomialLexOrdering());

Hi I think it is still alive somehow, see for example: http://maxima.sourceforge.net

Other systems? --znmeb, Sat, 17 Jun 2006 19:38:19 -0500 reply
Have we ruled out "special purpose" CAS packages, such as Ginac and Singular?

Dirac delta and piecewise --konstantin, Sun, 17 Sep 2006 13:33:02 -0500 reply
Dirak delta and piecewise was implemented as built-in in Mathematica: use DiracDelta?[x]? and Piecewise[{{-x,x<0},{x,x>0}}]?
