-*     .. Scalar Arguments ..
-      DOUBLE PRECISION ALPHA,BETA
-      INTEGER INCX,INCY,N

-*  Purpose
-*  =======
-*
-*  DSPMV  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   - 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  - DOUBLE PRECISION.
-*           On entry, ALPHA specifies the scalar alpha.
-*           Unchanged on exit.
-*
-*  AP     - DOUBLE PRECISION 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.
-*           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      - DOUBLE PRECISION 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.
-*
-*  BETA   - DOUBLE PRECISION.
-*           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      - DOUBLE PRECISION array of 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   - INTEGER.
-*           On entry, INCY specifies the increment for the elements of
-*           Y. INCY must not be zero.
-*           Unchanged on exit.
