WebSep 17, 2024 · 9.1: Sympy RREF function. In class we talked about the Python sympy library which has a “reduced row echelon form” (rref) function that runs a much more efficient version of the Gauss-Jordan function. To use the rref function you must first convert your matrix into a sympy.Matrix and then run the function.

Each row that contains a leading 1 has zeros everywhere else. All rows of 0 are in the bottom of the matrix. Then if A and B have different RREF, then their row space are different too. Why?
