+
+/* Purpose */
+/* ======= */
+
+/* CSPMV performs the matrix-vector operation */
+
+/* y := alpha*A*x + beta*y, */
+
+/* where alpha and beta are scalars, x and y are n element vectors and */
+/* A is an n by n symmetric matrix, supplied in packed form. */
+
+/* Arguments */
+/* ========== */
+
+/* UPLO (input) 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 (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. */
+
+/* AP (input) COMPLEX array, 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. */
+/* 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. */
+/* 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. */
+
+/* BETA (input) COMPLEX */
+/* On entry, BETA specifies the scalar beta. When BETA is */
+/* supplied as zero then Y need not be set on input. */
+/* Unchanged on exit. */
+
+/* Y (input/output) COMPLEX array, dimension at least */
+/* ( 1 + ( N - 1 )*abs( INCY ) ). */
+/* Before entry, the incremented array Y must contain the n */
+/* element vector y. On exit, Y is overwritten by the updated */
+/* vector y. */
+
+/* INCY (input) INTEGER */
+/* On entry, INCY specifies the increment for the elements of */
+/* Y. INCY must not be zero. */
+/* Unchanged on exit. */
