Hello,
I am looking for powerful vector (and possibly dyadic) CAS capabilities,
*without introducing components*.
Look at the following article:
http://www.apmaths.uwo.ca/~djeffrey/Offprints/LJcalculemus.pdf
In the interesting state-of-the-art part of this article, the authors
mention a Macsyma package, which is the work of Stoutemeyer, described in:
[12]. Stoutemyer, D.R., 1979. Symbolic computer vector analysis. Computers
& Mathematics with Applications, 5, 1-9.
It seems that David Stoutemyer contributes to this newsgroup from time to
time.
The package mentioned in [12] seems to be vect.mac. Can you confirm?
$ head share/vector/vect.mac
/*-*-MACSYMA-*-*/
eval_when(batch,ttyoff:true)$
/* Or use the BATCHLOAD command to load this with TTYOFF:TRUE */
/* NOTE: THE CURRENT VERSION OF VECT IS THE ONE DUE TO STOUTEMYER.
IT WILL BE REPLACED SOON BY AN EXTENDED VERSION WHICH HANDLES BOTH
VECTORS AND DYADICS.

So, this package should have been superseded by the work of Michael Wirth,
described in the following article:
SIAM J. Comput. 8, pp. 306-319
Symbolic Vector and Dyadic Analysis
Michael C. Wirth
http://epubs.siam.org/sicomp/resource/1/smjcat/v8/i3/p306_s1?isAuthorized=no
By looking in the source code of Macsyma, I find only one mention of
Michael Wirth:
$ grep -ril "wirth" *
share/vector/vect.mac
share/vector/vect.usg
Has the package of Wirth ever been commited?
What happened exactly?
Thanks in advance,
TP
