Provide a way to declare variables to be of vector or matrix type (with the consequence of being non-commutative in multiplication and a corresponding markup (like an overarrow or boldface typesetting or an underscore)

This would avoid symbolic simplifications which are valid only for scalar variables, see attachment.

Seems another case in wich zero-multiplication can't be simplified as zero.

SS-2384 added as related.

tested again with


No problems with matrix arguments any more, still wrong result with symbolic eval and scalar argument.
