Can you check something for me? Pivoting.

  1. Nov 1, 2009 #1
    1. The problem statement, all variables and given/known data

    14x1-12x2+3x3=41
    13x2+15x3=33
    15x2-16x3=53

    What row/column interchange must be completed for the next pivot element sing partial pivoting, scaled partial pivoting, and complete pivoting.


    I feel that with partial pivoting rows 2 and 3 should be switched. I'm confused about the other two, mainly because I can't find the info online like he said I could... but I feel the answer is the same in all cases. How wrong am I? :D
