WebTo get rref you usually have to divide one or more rows by a pivot coefficient, which changes the value of the determinant (to "one" if the matrix is invertible). When you just do a row operation like he did here, you're not dividing a row by a number, and so as you see in the video that doesn't change the value of the determinant. Comment 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.
