- 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
