    Do you mean diagonalize matrix A or a matrix made up of the diagonal entries of A.

    The command

    with(LinearAlgebra):

    D := Diagonal(A);

    Will choose just the diagonal entries from matrix A.


    For diagonalizing one... I'm not entirely sure but

    with(LinearAlgebra):

    D := JordanForm(A);

    Seems to be on the right track.
