hreal()

Usage:
hreal(hx), hx a REAL matrix representing complex data with Hermitian
  symmetry



Keywords: time series, complex arithmetic
                                  Usage
hreal(hx) computes the real part of the packed Hermitian matrix hx.  For
example, hreal(vector(1,2,3,4,5)) returns vector(1,2,3,3,2) and
hreal(vector(1,2,3,4,5,6)) returns vector(1,2,3 4,3,2).
