CDF2RDF

 

 Complex diagonal form to real block diagonal form.

  [V,D] = CDF2RDF(V,D) transforms the outputs of EIGMNUFU2 from complex

  diagonal form to a real diagonal form.  In complex diagonal form,

  D has complex eigenvalues down the diagonal.  In real diagonal

  form, the complex eigenvalues are in 2-by-2 blocks on the

  diagonal.  Complex eigenvalue pairs are assumed to be next

  to one another.
