CG, SCG - EISPACK routine. This subroutine calls the recommended
sequence of subroutines from the eigensystem subroutine package (EISPACK)
to find the eigenvalues and eigenvectors (if desired) of a COMPLEX
GENERAL matrix.

On INPUT
NNNNMMMM must be set to the row dimension of the two-dimensional array
parameters as declared in the calling program dimension statement.
NNNN is the order of the matrix A=(AR,AI).
AAAARRRR and AI contain the real and imaginary parts, respectively, of the
complex general matrix.
MMMMAAAATTTTZZZZ is an integer variable set equal to zero if only eigenvalues are
desired. Otherwise it is set to any non-zero integer for both
eigenvalues and eigenvectors. On OUTPUT
WWWWRRRR and WI contain the real and imaginary parts, respectively, of the
eigenvalues.
ZZZZRRRR and ZI contain the real and imaginary parts, respectively, of the
eigenvectors if MATZ is not zero.
IIIIEEEERRRRRRRR is an integer output variable set equal to an error completion code
described in section 2B of the documentation. The normal completion code
is zero.
FFFFVVVV1111 , FV2, and FV3 are temporary storage arrays. Questions and comments
should be directed to B. S. Garbow, APPLIED MATHEMATICS DIVISION, ARGONNE
