Can I define an n-dimensional matrix?
I'm sure this is a basic question that has been asked before but I'm too stupid to find it.
What I'd like to do is something like this
k=var('n') assume(n, 'integer') assume(n>0) VS = MatrixSpace(SR, n, 1)
to get the space of all n×1 matrices, i.e. column vectors. Is it at all possible to define a generalized n-dimensional vector or n×n matrix? Or am I just taking the completely wrong approach here?
Edit: Forgot to mention that the error I get is
ValueError: cannot convert n to int
