How can I delete the actual branch on trac and create a new one?
And: How do I merge properly to the recent beta version?
I am sorry, it seems I'm too stupid for git trac.

Damn it, I feel so stupid! :D Thanks, this did the job. :)

Actually, I get the error:

I think a lot of the matrix code is assumed to work over commutative rings,
but there is no assumption on them being fields. The MixedFormAlgebra is
not commutative, correct? If so, I think the best thing is to implement
what you need (i.e., the determinant) as a separate function for now.
Othe
Unfortunately, I noticed that the algorithm of computing the determinant of
MixedForm elements doesn't work for matrices of dimension higher than 3
since MixedFormAlgebra isin general not a field.
So, is it useful to create a new matrix class for this kind of purpose? If
so, how is the matrix i
Hello,
Having vector bundles would be nice! But what do you mean by
*abstract* vector bundle?
Ah. I meant vector bundles without specifying any maps. But since
changes of frames/coordinates and continuations are convenient to have,
this seems unavoidable. Where would you start if you'd program
