Positive definite matrix entries in Maple?

I've just started using Maple and I'm trying to solve an equation involving
matrices using isolve to solve for the entries in the matrix. At the moment
I have: isolve(convert(U+U^2-S, set)) (where the entries of U are unknown) I
would like to specify somehow that all the entries in the matrix U must be
positive. How do I do this without writing out explicity m_1,1 > 0, etc. for
every entry? Thanks.
