<p>Tela is a numerical computing environment mainly targeted for
numerical simulation pre- and postprocessing work. The language
supports arbitrary rank arrays (hence the name, Tensor Language), and
has powerful programming capabilities including F90 style vector
notation.</p>
<p>The on-line help is intended to be the primary source of
documentation. The command <b>help</b> (
help </a>
)
gives help of reserved words, intrinsic functions, standard functions,
and user functions. The function docview() can be used to view the
same documentation in plain ASCII form, in TeX DVI form, and in
Hypertext Markup Language (HTML) form. Right from the beginning you
should be familiar with the <b>help</b> command, and learn to browse the
HTML documentation. If you want a printed ``manual'', you can convert
the DVI files into PostScript using the standard TeX tool <b>dvips</b>
and print them.</p>
<p>The file you are now reading is the User's Guide. Other relevant document files
include
<a href="html:telahelp.html"> telahelp </a>
,
<a href="html:telafuncs.html"> telafuncs </a>
and
<a href="html:telafuncsSectioned.html"> telafuncsSectioned </a>
.
The <b>help</b> (
help </a>
) can retrieve the equivalent information.</p>
