+
+/* Purpose */
+/* ======= */
+
+/* CSYR performs the symmetric rank 1 operation */
+
+/* A := alpha*x*( x' ) + A, */
+
+/* where alpha is a complex scalar, x is an n element vector and A is an */
+/* n by n symmetric matrix. */
+
+/* Arguments */
+/* ========== */
+
+/* UPLO (input) CHARACTER*1 */
+/* On entry, UPLO specifies whether the upper or lower */
+/* triangular part of the array A is to be referenced as */
+/* follows: */
+
+/* UPLO = 'U' or 'u' Only the upper triangular part of A */
+/* is to be referenced. */
+
+/* UPLO = 'L' or 'l' Only the lower triangular part of A */
+/* is to be referenced. */
+
+/* Unchanged on exit. */
+
+/* N (input) INTEGER */
+/* On entry, N specifies the order of the matrix A. */
+/* N must be at least zero. */
+/* Unchanged on exit. */
+
+/* ALPHA (input) COMPLEX */
+/* On entry, ALPHA specifies the scalar alpha. */
+/* Unchanged on exit. */
+
+/* X (input) COMPLEX array, 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 (input) INTEGER */
+/* On entry, INCX specifies the increment for the elements of */
+/* X. INCX must not be zero. */
+/* Unchanged on exit. */
+
+/* A (input/output) COMPLEX array, dimension ( LDA, N ) */
+/* Before entry, with UPLO = 'U' or 'u', the leading n by n */
+/* upper triangular part of the array A must contain the upper */
+/* triangular part of the symmetric matrix and the strictly */
+/* lower triangular part of A is not referenced. On exit, the */
+/* upper triangular part of the array A is overwritten by the */
+/* upper triangular part of the updated matrix. */
+/* Before entry, with UPLO = 'L' or 'l', the leading n by n */
+/* lower triangular part of the array A must contain the lower */
+/* triangular part of the symmetric matrix and the strictly */
+/* upper triangular part of A is not referenced. On exit, the */
+/* lower triangular part of the array A is overwritten by the */
+/* lower triangular part of the updated matrix. */
+
+/* LDA (input) INTEGER */
+/* On entry, LDA specifies the first dimension of A as declared */
+/* in the calling (sub) program. LDA must be at least */
