I need to find all the sub-square matrices of a $4 \times 4$ matrix.
2. Then find the determinant of all $70$ of them.
I was directed to Sage but I know little about it. A simple program would be much appreciated.
For example, the matrix below:
$$2\quad 3\quad 1\quad 1$$
$$1\quad 2\quad 3\quad 1$$
$$1\quad 1\quad 2\quad 3$$
$$3\quad 1\quad 1\quad 2$$
Thanks to anyone who can help. Redbook1Thu, 15 Feb 2018 13:24:16 -0600https://ask.sagemath.org/question/41136/
