I don't fully understand your question, but if you mean you want to have
an "element-wise multiplication", then indeed this is *not* available in
lapackpp. The reason is that lapackpp is merely a wrapper to the
functionality that is offered by the numerical libraries LAPACK and
BLAS, and those don't have this operation (probably because in numerics
this operation is really never used). You will have to program it yoursel=
f.
