RG, SRG - 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 REAL 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.
AAAA contains the real 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. Complex conjugate pairs of eigenvalues appear consecutively
with the eigenvalue having the positive imaginary part first.
ZZZZ contains the real and imaginary parts of the eigenvectors if MATZ is
not zero. If the J-th eigenvalue is real, the J-th column of Z
contains its eigenvector. If the J-TH eigenvalue is complex with
positive imaginary part, the J-th and (J+1)-th columns of Z contain the
real and imaginary parts of its eigenvector. The conjugate of this
vector is the eigenvector for the conjugate eigenvalue.
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.
