How do I finish off my row-reducer in MATLAB?

  1. Mar 9, 2013 #1
    So far I have it so it'll take a matrix and put it in upper-triangular form, like any of these:

    Code (Text):

        1.0000    1.0000    4.5000    2.5000    4.0000
             0      1.0000    1.5000    0.1667    1.0000
             0             0   -1.0000    4.3333    8.0000
     
    Code (Text):

         1     1
         0     2
         0     4
         0     8
         0     0
         0     0
         0     2
         0     6

     
    Code (Text):

     1.0000    1.0000    0.8571    0.7143    5.0000
             0    1.0000   -0.7143   0.0714    8.0000
             0         0      1.0000    0.4535    8.0000
             0         0         0        1.0000    6.0000
             0         0         0         0           4.0000

     

    I'm at a loss as to how to finish it off. Thoughts?
