[GiNaC-list] Vector versus indexed (Was: extending symbol)

[jros]

It can be interesting for some of the guys following this discussion to
know about lib3d_mec-ginac. The version at the www is not up to date,
but if some one wants it I can send a copy.

I'm supporting vector algebra using 3-tuple and 3x3-matrixes, but I was
planning to support vector types similar the ones that you are defining.

Cheers,

Javier.
