+
+/* Purpose */
+/* ======= */
+
+/* Level 3 BLAS like routine for C in RFP Format. */
+
+/* DSFRK performs one of the symmetric rank--k operations */
+
+/* C := alpha*A*A' + beta*C, */
+
+/* or */
+
+/* C := alpha*A'*A + beta*C, */
+
+/* where alpha and beta are real scalars, C is an n--by--n symmetric */
+/* matrix and A is an n--by--k matrix in the first case and a k--by--n */
+/* matrix in the second case. */
+
+/* Arguments */
+/* ========== */
+
+/* TRANSR (input) CHARACTER */
+/* = 'N': The Normal Form of RFP A is stored; */
+/* = 'T': The Transpose Form of RFP A is stored. */
+
+/* UPLO - (input) CHARACTER */
+/* On entry, UPLO specifies whether the upper or lower */
+/* triangular part of the array C is to be referenced as */
+/* follows: */
+
+/* UPLO = 'U' or 'u' Only the upper triangular part of C */
+/* is to be referenced. */
+
+/* UPLO = 'L' or 'l' Only the lower triangular part of C */
+/* is to be referenced. */
+
+/* Unchanged on exit. */
+
+/* TRANS - (input) CHARACTER */
+/* On entry, TRANS specifies the operation to be performed as */
+/* follows: */
+
+/* TRANS = 'N' or 'n' C := alpha*A*A' + beta*C. */
+
+/* TRANS = 'T' or 't' C := alpha*A'*A + beta*C. */
+
+/* Unchanged on exit. */
+
+/* N - (input) INTEGER. */
+/* On entry, N specifies the order of the matrix C. N must be */
+/* at least zero. */
+/* Unchanged on exit. */
+
+/* K - (input) INTEGER. */
+/* On entry with TRANS = 'N' or 'n', K specifies the number */
+/* of columns of the matrix A, and on entry with TRANS = 'T' */
+/* or 't', K specifies the number of rows of the matrix A. K */
+/* must be at least zero. */
+/* Unchanged on exit. */
+
+/* ALPHA - (input) DOUBLE PRECISION. */
+/* On entry, ALPHA specifies the scalar alpha. */
+/* Unchanged on exit. */
+
+/* A - (input) DOUBLE PRECISION array of DIMENSION ( LDA, ka ), where KA */
+/* is K when TRANS = 'N' or 'n', and is N otherwise. Before */
+/* entry with TRANS = 'N' or 'n', the leading N--by--K part of */
+/* the array A must contain the matrix A, otherwise the leading */
+/* K--by--N part of the array A must contain the matrix A. */
+/* Unchanged on exit. */
+
+/* LDA - (input) INTEGER. */
+/* On entry, LDA specifies the first dimension of A as declared */
+/* in the calling (sub) program. When TRANS = 'N' or 'n' */
+/* then LDA must be at least max( 1, n ), otherwise LDA must */
+/* be at least max( 1, k ). */
+/* Unchanged on exit. */

+/* BETA - (input) DOUBLE PRECISION. */
