## Functions/Subroutines

subroutine srscl (N, SA, SX, INCX)
SRSCL multiplies a vector by the reciprocal of a real scalar.

## Function/Subroutine Documentation

 subroutine srscl ( integer N, real SA, real, dimension( * ) SX, integer INCX )

SRSCL multiplies a vector by the reciprocal of a real scalar.

Purpose:
``` SRSCL multiplies an n-element real vector x by the real scalar 1/a.
This is done without overflow or underflow as long as
the final result x/a does not overflow or underflow.```
Parameters:
 [in] N ``` N is INTEGER The number of components of the vector x.``` [in] SA ``` SA is REAL The scalar a which is used to divide each component of x. SA must be >= 0, or the subroutine will divide by zero.``` [in,out] SX ``` SX is REAL array, dimension (1+(N-1)*abs(INCX)) The n-element vector x.``` [in] INCX ``` INCX is INTEGER The increment between successive values of the vector SX. > 0: SX(1) = X(1) and SX(1+(i-1)*INCX) = x(i), 1< i<= n```
