Support Multidimentional

SymPy tensors is probably the way to go, but I haven't looked at it yet.

Support Multidimentional

I saw this upstream: https://github.com/sympy/sympy/pull/11800, so looks like its do-able now/soonish.

Support Multidimentional

Thanks @Upabjojr you're very welcome to help us here if you'd like! My feeling is this task might be easier after we have a better communication mechanism between Octave and...

Replace python is_A to isinstance(*, A)

hmmm, `None` is an annoying special case where calling `is_Symbol` is an error, because `S(None)` is just `None` and not a Sympy object. Could be a good to have a...

unhelpful error when a symfun is given as indep variable in creation of symfun

These seem to involve putting symfun's as independent variables: really not sure why we expect that to work. E.g., in your second example, `t` is a symfun. The error messages...

unhelpful error when a symfun is given as indep variable in creation of symfun

Do you know if any of this stuff works in SMT?

unhelpful error when a symfun is given as indep variable in creation of symfun

new title ok?

unhelpful error when a symfun is given as indep variable in creation of symfun

FWIW, your "practical example" does not work in SMT.

limit(1/x,x,0) without direction should be NaN

Improve SolverSet

Sounds like it will it eventually replace `solve` in upstream SymPy, but not yet. Maybe we could try an "experimental" `@sym/solveset` that calls it for now?
