+/*  ======= */
+
+/*  DPOTRF computes the Cholesky factorization of a real symmetric */
+/*  positive definite matrix A. */
+
+/*  The factorization has the form */
+/*     A = U**T * U,  if UPLO = 'U', or */
+/*     A = L  * L**T,  if UPLO = 'L', */
+/*  where U is an upper triangular matrix and L is lower triangular. */
+
+/*  This is the block version of the algorithm, calling Level 3 BLAS. */

+/*          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 */
