Hi Nicolas
Learned a little about the Categories setup
Next step is to override the __repr__ method
Is the "B[word: ]" string formed in a __str__ or __repr__ method?
If so, Im trying to work out where it is (so I can base the new code on it)
I ran these...
sage: C = AlgebrasWithBasis(QQ)
sa
Nicolas
C = AlgebrasWithBasis(QQ)
C?
certainly did report back more info!
And the categories seem to be the very classes needed for "abstract matrices"!
Its a bit time-consuming to get on top of this if one is new to
Categories (like me ;-) but the amount of functionality that you
inherit makes

This intrigued me, so I did exactly the above; and found that I could

Hi
Id like to write a package that can do "pure"/"abstract" matrix
expressions such as in the following examples
To keep things simple, in the examples below, let
A, B, C... be matrices; k be a scalar
"*" be matrix or scalar multiplication, "^-1" and "^T" and "^n" be
matrix inverse, transpose and
