I want to use the JacobianMatrix
function in package VectorAnalysis
, but I get the following warning message after running the following code.
Needs["VectorAnalysis`"]
JacobianMatrix[{Rr, Ttheta, Zz}, Cylindrical]
General::obspkg: VectorAnalysis` is now obsolete. The legacy version being loaded may conflict with current functionality. See the Compatibility Guide for updating information.
But I didn't find the same function in the built-in functions. What should I do to reproduce this function.
I want to reproduce the function in various common coordinate systems.
JacobianMatrix
in the document and the solution is in VectorAnalysis` Compatibility Information. (The first link in v9 and the second link in v12.1. ) $\endgroup$D[{r Cos[\[Theta]], r Sin[\[Theta]], z}, {{r, \[Theta], z}, 1}]
? It is unambiguous, concise, and universally applicable (i.e., not limited to a few hard-coded transformations). $\endgroup$
