Fast Polar Decomposition Of A sTrAnGe Square Matrix - Help

  1. Sep 14, 2008 #1
    Fast Polar Decomposition Of A sTrAnGe Square Matrix --!!Help!!

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

    | 2 0 4 |
    | 0 1 0 | = A
    | 3 0 2 |


    Calculate the Polar Decomposition of A: [tex]A = LP[/tex]

    [tex]L =^{t}L > 0[/tex] L is symmetric and positive defined

    [tex] P^{t}P = I[/tex]

    [tex]^{t}P=P^{-1}[/tex] P is an isometry: Transpose of P is egual to P^-1


    Is there a quick way to do this?????
    I know how to do it but is very slow, and I think that must exists a quick way or some tricks to resolve the exercise, infact as you can see the matrix is very particular...

    Help Me please....Tnx
