sscal(3P)		    Sun Performance Library		     sscal(3P)

NAME
       sscal - Compute y := alpha * y

SYNOPSIS
       SUBROUTINE SSCAL(N, ALPHA, Y, INCY)

       INTEGER N, INCY
       REAL ALPHA
       REAL Y(*)

       SUBROUTINE SSCAL_64(N, ALPHA, Y, INCY)

       INTEGER*8 N, INCY
       REAL ALPHA
       REAL Y(*)

   F95 INTERFACE
       SUBROUTINE SCAL([N], ALPHA, Y, [INCY])

       INTEGER :: N, INCY
       REAL :: ALPHA
       REAL, DIMENSION(:) :: Y

       SUBROUTINE SCAL_64([N], ALPHA, Y, [INCY])

       INTEGER(8) :: N, INCY
       REAL :: ALPHA
       REAL, DIMENSION(:) :: Y

   C INTERFACE
       #include <sunperf.h>

       void sscal(int n, float alpha, float *y, int incy);

       void sscal_64(long n, float alpha, float *y, long incy);

PURPOSE
       sscal Compute y := alpha * y where alpha is a scalar and y is an n-vec‐
       tor.

ARGUMENTS
       N (input)
		 On entry, N specifies the number of elements in  the  vector.
		 N must be at least one for the subroutine to have any visible
		 effect.  Unchanged on exit.

       ALPHA (input)
		 On entry, ALPHA specifies the	scalar	alpha.	 Unchanged  on
		 exit.

       Y (input/output)
		 (  1  +  ( n - 1 )*INCY ).  On entry, the incremented array Y
		 must contain the vector y. On exit, Y is overwritten  by  the
		 updated vector y.

       INCY (input)
		 On entry, INCY specifies the increment for the elements of Y.
		 This routine returns immediately if  INCY  is	less  than  or
		 equal to zero.	 Unchanged on exit.
