The itensor package provides limited support for exporting tensor
expressions to TeX. Since itensor expressions appear as function calls,
the regular Maxima tex command will not produce the expected
output. You can try instead the tentex command, which attempts
to translate tensor expressions into appropriately indexed TeX objects.
To use the tentex function, you must first load tentex,
as in the following example:
(%i1) load("itensor")$
(%i2) load("tentex")$
(%i3) idummyx:m;
(%o3) m
(%i4) ishow(icurvature([j,k,l],[i]))$
m1 i m1 i i
(%t4) ichr2 ichr2 - ichr2 ichr2 - ichr2
j k m1 l j l m1 k j l,k
i
+ ichr2
j k,l
(%i5) tentex(%)$
$$\Gamma_{j\,k}^{m_1}\,\Gamma_{l\,m_1}^{i}-\Gamma_{j\,l}^{m_1}\,
\Gamma_{k\,m_1}^{i}-\Gamma_{j\,l,k}^{i}+\Gamma_{j\,k,l}^{i}$$
Note the use of the idummyx assignment, to avoid the appearance
of the percent sign in the TeX expression, which may lead to compile errors.
NB: This version of the tentex function is somewhat experimental.
