+/* ======= */
+
+/* SSPR2 performs the symmetric rank 2 operation */
+
+/* A := alpha*x*y' + alpha*y*x' + A, */
+
+/* where alpha is a scalar, x and y are n element vectors and A is an */
+/* n by n symmetric matrix, supplied in packed form. */
+
+/* Arguments */
+/* ========== */
+
+/* UPLO - CHARACTER*1. */
+/* On entry, UPLO specifies whether the upper or lower */
+/* triangular part of the matrix A is supplied in the packed */
+/* array AP as follows: */
+
+/* UPLO = 'U' or 'u' The upper triangular part of A is */
+/* supplied in AP. */
+
+/* UPLO = 'L' or 'l' The lower triangular part of A is */
+/* supplied in AP. */
+
+/* Unchanged on exit. */
+
+/* N - INTEGER. */
+/* On entry, N specifies the order of the matrix A. */
+/* N must be at least zero. */
+/* Unchanged on exit. */
+
+/* ALPHA - REAL . */
+/* On entry, ALPHA specifies the scalar alpha. */
+/* Unchanged on exit. */
+
+/* X - REAL array of dimension at least */
+/* ( 1 + ( n - 1 )*abs( INCX ) ). */
+/* Before entry, the incremented array X must contain the n */
+/* element vector x. */
+/* Unchanged on exit. */
+
+/* INCX - INTEGER. */
+/* On entry, INCX specifies the increment for the elements of */
+/* X. INCX must not be zero. */
+/* Unchanged on exit. */
+
+/* Y - REAL array of dimension at least */
+/* ( 1 + ( n - 1 )*abs( INCY ) ). */
+/* Before entry, the incremented array Y must contain the n */
+/* element vector y. */
+/* Unchanged on exit. */
+
+/* INCY - INTEGER. */
+/* On entry, INCY specifies the increment for the elements of */
+/* Y. INCY must not be zero. */
+/* Unchanged on exit. */
+
+/* AP - REAL array of DIMENSION at least */
+/* ( ( n*( n + 1 ) )/2 ). */
+/* Before entry with UPLO = 'U' or 'u', the array AP must */
+/* contain the upper triangular part of the symmetric matrix */
+/* packed sequentially, column by column, so that AP( 1 ) */
+/* contains a( 1, 1 ), AP( 2 ) and AP( 3 ) contain a( 1, 2 ) */
+/* and a( 2, 2 ) respectively, and so on. On exit, the array */
+/* AP is overwritten by the upper triangular part of the */
+/* updated matrix. */
+/* Before entry with UPLO = 'L' or 'l', the array AP must */
+/* contain the lower triangular part of the symmetric matrix */
+/* packed sequentially, column by column, so that AP( 1 ) */
+/* contains a( 1, 1 ), AP( 2 ) and AP( 3 ) contain a( 2, 1 ) */
+/* and a( 3, 1 ) respectively, and so on. On exit, the array */
