- NNNNAAAAMMMMEEEE
- HTRIB3, SHTRIB3 - EISPACK routine. This subroutine forms the
- eigenvectors of a COMPLEX HERMITIAN matrix by back transforming those of
- the corresponding real symmetric tridiagonal matrix determined by
- HTRID3.

- On INPUT
-
- NNNNMMMM must be set to the row dimension of two-dimensional array parameters
- as declared in the calling program dimension statement.
-
- NNNN is the order of the matrix.
-
- AAAA contains information about the unitary transformations used in the
- reduction by HTRID3.
-
- TTTTAAAAUUUU contains further information about the transformations.
-
- MMMM IS the number of eigenvectors to be back transformed.
-
- ZZZZRRRR contains the eigenvectors to be back transformed in its first M
- columns. On OUTPUT
-
- ZZZZRRRR and ZI contain the real and imaginary parts, respectively, of the
- transformed eigenvectors in their first M columns. NOTE that the last
- component of each returned vector is real and that vector Euclidean norms
- are preserved. Questions and comments should be directed to B. S.
