It’s already possible with the package; however, I have not published all the code for it yet since it is not fully completed in its implementation yet.
You will be able to work with matrices too. However, I recommend against using matrices, because my package is all about geometric algebra, which uses multivectors instead of matrices.
The philosophy of my paper is encoded in “differential geometric algebra” which is a generalization of what is called linear algebra and multi-linear algebra, which also includes differential + geometric algebra too. That is why I am making my package, because this has not been done before in that way.
The whole point of my package is to use * the multiplication for this purpose.
