Hi,
I am brand-new to using maxima. I wanted to use
the ctensr package, but had the following problem
with tsetup():
(C3) tsetup();
enter the dimension of the coordinate system:
2;
do you wish to change the coordinate names?
no;
do you want to
1. enter a new metric?
2. enter a metric from a file?
3. approximate a metric with a taylor series?
1;
Is the matrix 1. Diagonal 2. Symmetric 3.
Antisymmetric 4. General
Answer 1, 2, 3 or 4 : 1;
Row 1 Column 1: x^3;
Row 2 Column 2: x^2;
Matrix entered.
enter functional dependencies with the depends
function or 'n' if none
no;
do you wish to see the metric?
yes;
[ 3 ]
[ x 0 ]
[ ]
[ 2 ]
[ 0 x ]
Improper argument to IDENT:
2
#0: metric()(ctensr.mac line 161)
#1: newmet()(ctensr.mac line 119)
#2: PRED(opt=1)(ctensr.mac line 107)
-- an error. Quitting. To debug this try
DEBUGMODE(TRUE);)
(C4)
On futher investigation, I get the following
problem with ident (2):
(C4) ident(2);
Improper argument to IDENT:
2
-- an error. Quitting. To debug this try
DEBUGMODE(TRUE);)
(C5)
I am using maxima 5.9.0 with clisp 2.33 (both
built from source on a home-compiled linux system).
Has anyone else seen this problem? If so, does
anyone have a fix? I searched through the bugs on
the maxima site, but did not find anything related
to ident and tsetup.
Thanks,
David Reese
