Query: A note on some extensions of the matrix angular central Gaussian
  distribution   This paper extends the notion of the matrix angular central distribution
(MACG) to the complex case. We start by considering the normally distributed
random complex matrix ($Z$) and show that is the orientation
($H_Z=Z(Z'Z)^{-1}$) has complex MACG (CMACG) distribution. Then we discuss the
distribution of the orientation of the linear transformation of the random
matrix which orientation part has CMACG distribution. Finally, we discuss the
family of distributions which lead to the CMACG distribution.
