himag(hx), hx a REAL matrix representing complex data with Hermitian

Keywords: time series, complex arithmetic
himag(hx) computes the imaginary part of the packed Hermitian matrix hx.
For examplem, himag(vector(1,2,3,4,5)) is vector(0,5,4,-4,-5) and
himag(vector(1,2,3,4,5,6)) is vector(0,6,5,0,-5,-6).
