 *  Arguments
 *  =========
 *
-*  UPLO    (input) CHARACTER*1
-*          = 'U':  Upper triangle of A is stored;
-*          = 'L':  Lower triangle of A is stored.
-*
-*  N       (input) INTEGER
-*          The order of the matrix A.  N >= 0.
-*
-*  A       (input/output) DOUBLE PRECISION array, dimension (LDA,N)
-*          On entry, the symmetric matrix A.  If UPLO = 'U', the leading
-*          N-by-N upper triangular part of A contains the upper
-*          triangular part of the matrix A, and the strictly lower
-*          triangular part of A is not referenced.  If UPLO = 'L', the
-*          leading N-by-N lower triangular part of A contains the lower
-*          triangular part of the matrix A, and the strictly upper
-*          triangular part of A is not referenced.
-*          On exit, if UPLO = 'U', the diagonal and first superdiagonal
-*          of A are overwritten by the corresponding elements of the
-*          tridiagonal matrix T, and the elements above the first
-*          superdiagonal, with the array TAU, represent the orthogonal
-*          matrix Q as a product of elementary reflectors; if UPLO
-*          = 'L', the diagonal and first subdiagonal of A are over-
-*          written by the corresponding elements of the tridiagonal
-*          matrix T, and the elements below the first subdiagonal, with
-*          the array TAU, represent the orthogonal matrix Q as a product
-*          of elementary reflectors. See Further Details.
-*
-*  LDA     (input) INTEGER
-*          The leading dimension of the array A.  LDA >= max(1,N).
-*
-*  D       (output) DOUBLE PRECISION array, dimension (N)
-*          The diagonal elements of the tridiagonal matrix T:
-*          D(i) = A(i,i).
-*
-*  E       (output) DOUBLE PRECISION array, dimension (N-1)
-*          The off-diagonal elements of the tridiagonal matrix T:
-*          E(i) = A(i,i+1) if UPLO = 'U', E(i) = A(i+1,i) if UPLO = 'L'.
-*
-*  TAU     (output) DOUBLE PRECISION array, dimension (N-1)
-*          The scalar factors of the elementary reflectors (see Further
-*          Details).
