Thanks for the reply! But the example you posted has complex e.vals which are conjugates of each other with +ve real part, hence the trace and det condition will be satisfied without the e.vals being (real) positive.

Here is a 'simple' 3-line proof for this statement!
(Although the simplicity hides behind the form and properties of the matrix geometric mean.)
