+/*  Purpose */
+/*  ======= */
+
+/*  DPOTF2 computes the Cholesky factorization of a real symmetric */
+/*  positive definite matrix A. */
+
+/*  The factorization has the form */
+/*     A = U' * U ,  if UPLO = 'U', or */
+/*     A = L  * L',  if UPLO = 'L', */
+/*  where U is an upper triangular matrix and L is lower triangular. */
+
+/*  This is the unblocked version of the algorithm, calling Level 2 BLAS. */
+
+/*  Arguments */
+/*  ========= */
+
+/*  UPLO    (input) CHARACTER*1 */
+/*          Specifies whether the upper or lower triangular part of the */
+/*          symmetric matrix A is stored. */

+/*          = 'L':  Lower triangular */

+/*          The order of the matrix A.  N >= 0. */

+/*          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 */
