+
+/*  Purpose */
+/*  ======= */
+
+/*  DPPSV computes the solution to a real system of linear equations */
+/*     A * X = B, */
+/*  where A is an N-by-N symmetric positive definite matrix stored in */
+/*  packed format and X and B are N-by-NRHS matrices. */
+
+/*  The Cholesky decomposition is used to factor A as */
+/*     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 a lower triangular */
+/*  matrix.  The factored form of A is then used to solve the system of */
+/*  equations A * X = B. */
+
+/*  Arguments */
+/*  ========= */
+
+/*  UPLO    (input) CHARACTER*1 */
+/*          = 'U':  Upper triangle of A is stored; */
+/*          = 'L':  Lower triangle of A is stored. */
+
+/*  N       (input) INTEGER */
+/*          The number of linear equations, i.e., the order of the */
+/*          matrix A.  N >= 0. */
+
+/*  NRHS    (input) INTEGER */
+/*          The number of right hand sides, i.e., the number of columns */
+/*          of the matrix B.  NRHS >= 0. */
+
+/*  AP      (input/output) DOUBLE PRECISION array, dimension (N*(N+1)/2) */
+/*          On entry, the upper or lower triangle of the symmetric matrix */
+/*          A, packed columnwise in a linear array.  The j-th column of A */
+/*          is stored in the array AP as follows: */
+/*          if UPLO = 'U', AP(i + (j-1)*j/2) = A(i,j) for 1<=i<=j; */
+/*          if UPLO = 'L', AP(i + (j-1)*(2n-j)/2) = A(i,j) for j<=i<=n. */
+/*          See below for further details. */
+
+/*          On exit, if INFO = 0, the factor U or L from the Cholesky */
+/*          factorization A = U**T*U or A = L*L**T, in the same storage */
+/*          format as A. */
+
+/*  B       (input/output) DOUBLE PRECISION array, dimension (LDB,NRHS) */
+/*          On entry, the N-by-NRHS right hand side matrix B. */
+/*          On exit, if INFO = 0, the N-by-NRHS solution matrix X. */
+
+/*  LDB     (input) INTEGER */
+/*          The leading dimension of the array B.  LDB >= max(1,N). */

+/*          < 0:  if INFO = -i, the i-th argument had an illegal value */
+/*          > 0:  if INFO = i, the leading minor of order i of A is not */
+/*                positive definite, so the factorization could not be */
+/*                completed, and the solution has not been computed. */
+
+/*  Further Details */
+/*  =============== */
+
+/*  The packed storage scheme is illustrated by the following example */
+/*  when N = 4, UPLO = 'U': */
+
+/*  Two-dimensional storage of the symmetric matrix A: */
+
+/*     a11 a12 a13 a14 */
+/*         a22 a23 a24 */
+/*             a33 a34     (aij = conjg(aji)) */
+/*                 a44 */
+
+/*  Packed storage of the upper triangle of A: */

+/*  AP = [ a11, a12, a22, a13, a23, a33, a14, a24, a34, a44 ] */
