Absolutely agree, dimensionality 2 is a must. For two reasons. First, it's easy to understand and implement. Second it actively discourages those who would like to use this matrix for real calculations. The main point is basic and simple: teaching, geometry computation (e.g. on point rotation/translation) etc. Things like that. Anything else is beyond the scope of such a module and should be implemented using numpy. Calculations about determinant, element-wise operations, matrix multiplication, inverse, etc are also basic operations that are likely to come up during either a course or trivial computations for e.g. geometry. I would not add things like QR or Cholesky factorization. -- Kind regards, Stefano Borini _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/UQDBXSVCLARFIGNIZPYGIJ5S4M7VPMCO/ Code of Conduct: http://python.org/psf/codeofconduct/
