What I mean is: rref([4 5 2 0; 2 7 9 0; 8 10 4 0]) results in [ 1 0 -1.7222 0; 0 1 1.7777 0; 0 0 0 0] This is an example, where each row starts with a one, that the colunm that contains a starting one is all zeros save that one, and the matrix is an upper triangular matrix. Your method is close to what I am looking for but not quite. Hopefully this will make clearer what I am looking for. ---------------------------------------------------------------------------- | "For to me to live is Christ, and to die is gain." | | --- Philippians 1:21 (KJV) | ---------------------------------------------------------------------------- | Ryan Kirkpatrick | Boulder, Colorado | rkirkpat at nag dot cs dot colorado dot edu| | ---------------------------------------------------------------------------- | http://www-ugrad.cs.colorado.edu/~rkirkpat/ | ----------------------------------------------------------------------------
