[sympy] How to create a vector function in sympy with actual vectors, that can be transformed between coordinate systems?

I saw this https://stackoverflow.com/questions/46993819/how-to-create-a-vector-function-in-sympy which uses Matrix() as a workaround to create a vector. The author says, that it can not be transformed between coordinate systems, like real vectors, though. I need to transform my input and o

Asymptote is capable of creating high-quality drawings, on par with what you would find in Springer books. I feel it produces superior results. Am Do., 11. Nov. 2021 um 14:02 Uhr schrieb Alan Bromborsky < abrombo...@gmail.com>: > FYI attached is a figure I generated with Asymptote for a Foucault
