Interpreting the meaning of the RREF of the column space of a matrix
May 26, 2022 · Recall that for finding the row space of a matrix $A$, you just compute the Reduced Row Echelon Form (RREF) of $A$ and then take the non-zero rows of $\text {rref} (A)$ as vectors in the …
Best way to find Reduced Row Echelon Form (rref) of a matrix?
