Homework Help: Pseudo Inverse & QR Decomposition

  1. Dec 21, 2008 #1
    1. The problem statement, all variables and given/known data

    Let A[tex]\in[/tex]Rmxn be factorized as A=QR where Q[tex]\in[/tex]Rmxn has orthonormal columns. Prove that A+=R+QT

    2. Relevant equations

    R is an upper triangular matrix

    3. The attempt at a solution

    I tried to apply the definition A+=(ATA)+A+
    I ended up here: R+(RR+)TQT
    I'm not sure if i am going in the right direction
    thanks for your assistance
