cdiag()

Usage:
d <- cdiag(a), REAL matrix a representing the fully complex form of a
  square complex matrix A



Keywords: complex matrices, matrices
                                  Usage
d <- cdiag(a), where a is a REAL matrix representing a square complex
matrix A in fully complex form.

d is a nrows(a) by 2 REAL matrix representing diag(A) in fully complex
form.

It is an error for A to not be square, that is for ncols(a) != 2*nrows(a)
and ncols(a) != 2*nrows(a) - 1.
