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:
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+(N-1)*abs(INCX)) The n-element vector x.
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
