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
