ZDRSCL(1) LAPACK auxiliary routine (version 3.2) ZDRSCL(1)NAME
ZDRSCL - multiplies an n-element complex vector x by the real scalar
1/a
SYNOPSIS
SUBROUTINE ZDRSCL( N, SA, SX, INCX )
INTEGER INCX, N
DOUBLE PRECISION SA
COMPLEX*16 SX( * )
PURPOSE
ZDRSCL multiplies an n-element complex 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.
ARGUMENTS
N (input) INTEGER
The number of components of the vector x.
SA (input) DOUBLE PRECISION
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) COMPLEX*16 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
