Attached is a jupyter notebook that runs Sage 9.1, a (slightly more) minimal example of a problem that I discovered. When calculating the determinant of a large (in the sense n>=9 I have currently found) symbolic matrix the answer is not correct....
I've tried to translate this into a plain sage script (for the command-line) to get a minimal example. Really, all we need is the matrices, but I ran into some trouble with indices in the Qsimplify=True branch. That could mean I don't know enough about Jupyter, but it also might just mean that there's a bug in that part of the code.
Is this still a problem for you? If so, can you try to reproduce only the two (equivalent) matrices whose determinants are different? The sage_input() function might be of some help here. Ideally the example would look like
<some variable definitions> A = matrix(...) B = matrix(...) A.det() == B.det() -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
