Khan Academy Rref . Operational linear algebra sucks without one. Ok, however by doing this i ended up a question:

My interpretation of ref is just doing row operations in such a way to avoid dividing rows by their pivot values (to make the pivot become 1). I am using khan academy as my main study tool and benchmark while supplementing it with other resources. The basis of the col space is the pivot columns of the original matrix, and pivot columns are most easily identified by looking at the rref of the matrix.

If you go through each pivot (the numbers along the diagonal) and divide those rows by their leading coefficient, then you will end up in rref. Anyway there's not trick, just following the steps. We'll use this thread to keep track. I know khan academy is good on this topic. Rule (r3) is replaced by rule (rr3) a matrix is.

(that is, rref is the name of the operator that does rref.) most do not have a ref operator reduced row echelon form de nition we give a de nition of rref that is similar to the text’s ref on page 2. Rule (r3) is replaced by rule (rr3) a matrix is in reduced row echelon form if. Khan academy.
