SRSCL multiplies a vector by the reciprocal of a real scalar.
Download SRSCL + dependencies [TGZ] [ZIP] [TXT]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.
[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+(N1)*abs(INCX)) The nelement vector x. 
[in]  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
