SRSCL(l) ) SRSCL(l)
SRSCL - multiplie an n-element real vector x by the real scalar 1/a
SUBROUTINE SRSCL( N, SA, SX, INCX )
INTEGER INCX, N
REAL SX( * )
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.
N (input) INTEGER
The number of components of the vector x.
SA (input) 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 (input/output) REAL array, dimension
(1+(N-1)*abs(INCX)) The n-element vector x.
INCX (input) 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
