M = Matrix([0], ring=GF(4))
M
Prints "[0]" as expected. The inverse of M clearly does not exist. Even so, running
M.inverse()
does not throw an error, and instead prints "[1]". What's going on here?
I am running Sage 8.1. Thanks for the help.brantmvThu, 16 Jul 2020 04:15:30 +0200https://ask.sagemath.org/question/52487/
