NAME
SRC/crscl.f

SYNOPSIS

  Functions/Subroutines
subroutine crscl (n, a, x, incx)
CRSCL multiplies a vector by the reciprocal of a real scalar.

Function/Subroutine Documentation

  subroutine crscl (integer n, complex a, complex, dimension( * ) x, integer incx)

CRSCL multiplies a vector by the reciprocal of a real scalar.

Purpose:

     CRSCL multiplies an n-element complex vector x by the complex 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.

    A

              A is COMPLEX
              The scalar a which is used to divide each component of x.
              A must not be 0, or the subroutine will divide by zero.

    X

              X is COMPLEX array, dimension
                             (1+(N-1)*abs(INCX))
              The n-element vector x.

    INCX

              INCX is INTEGER
              The increment between successive values of the vector X.
              > 0:  X(1) = X(1) and X(1+(i-1)*INCX) = x(i),     1< i<= n
