    eigen value power method excel

    hello
    I am try implement power method for finding eigen value and vector in excel for 3x3 M.
    I find first one ok, i then with matrix (M) do: M- eigval . eigvec . eigvecT
    where t is transpose.
    I then do power method again but it stop working and give me the same eigen value but negative, and I know this not right.

    would anyone allow me to send them my excel sheet and they can see what i do wrong? Would be very much appreciate.

    Thank you very much

    Just attach the spread sheet to a post (if not already using it go to the advanced editor, scroll down to the Manage Attachments button, and proceed from there).
