Where do I find the matrix commands Ref and Rref on my 9860G AU PLUS (or updated 9860g AU)?
When using a 9860G AU PLUS (or 9860G AU with OS 1.05 or later) to work with matrices, the commands Ref (row echelon form) and Rref (reduced row echelon form) can be useful. These are found from within q by pressing i then MAT (w) then u to see more commands then either Ref (r) or Rref (y).
