NAME
srscl.f 
SYNOPSIS
Functions/Subroutines
subroutine srscl (N, SA, SX, INCX)
SRSCL multiplies a vector by the reciprocal of a real scalar.
Function/Subroutine Documentation
subroutine srscl (integerN, realSA, real, dimension( * )SX, integerINCX)
SRSCL multiplies a vector by the reciprocal of a real scalar.
Purpose:
SRSCL multiplies an nelement 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:
N
N is INTEGER
The number of components of the vector x.
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.
SX
SX is REAL array, dimension
(1+(N1)*abs(INCX))
The nelement vector x.
INCX
INCX is INTEGER
The increment between successive values of the vector SX.
> 0: SX(1) = X(1) and SX(1+(i1)*INCX) = x(i), 1< i<= n
