Rref by hand
WebJun 18, 2024 · I don't think RREF is particularly useful other than for teaching linear algebra to college students, so your best hope is to find some math professor who uses Emacs and was sick of doing RREF by hand while grading homework... someone like me! Here's a little package I wrote the first time I taught linear algebra:

Since A is in RREF (in fact, A = I4 is the 4 × 4 identity matrix), we can immediately conclude that the matrix equation Ax = b has the solution x = b for any choice of b. Moreover, as we will see in Section A.4.2, x = b is the only solution to this system. 2.
