Problem With MATLAB RREF Function Returning Trivial Solution.

  1. Feb 7, 2012 #1
    I'm trying to solve a system of linearly dependent equations. I solved the first set no problem, but for some reason MATLAB is returning the trivial solution for the second one, can anyone explain why?

    Systems:
    eq1 =
    -29.7250 -3.0000 0
    -3.0000 -0.3028 0
    eq2 =
    2.7250 -3.0000 0
    -3.0000 3.3028 0

    Solutions
    u1 =
    1.0000 0.1009 0
    0.0000 0.0000 0
    u2 =
    1 0 0
    0 1 0

    The first solution, u1, is what I expected, however, the second solution is not. If I do it by hand, I get:
    eq2 =
    1.0000 -1.1009 0
    0.0000 0.0000 0

    Thanks!
