NAME
     cdotu - Compute the dot product of two vectors x and y.

SYNOPSIS
     COMPLEX FUNCTION CDOTU (N, X, INCY, Y, INCY )

     complex *cdotu (int n, complex *cx, int incx,  complex  *cy,
               int incy);

     INTEGER INCX, INCY, N

     COMPLEX X( * ), Y( * )

PURPOSE
     CDOTU - Compute the dot product of x and y where x and y are
     n-vectors.


PARAMETERS
     N         - INTEGER.
               On entry, N specifies the number  of  elements  in
               the  vector.   If N is not positive then the func-
               tion returns the value 0.0.  Unchanged on exit.

     X         - COMPLEX array
               of DIMENSION at least ( 1 + ( n - 1 )*abs( INCX  )
               ).  On entry, the incremented array X must contain
               the vector x.  On exit, the y vector.

     INCX      - INTEGER.
               On entry, INCX specifies  the  increment  for  the
               elements  of  X. INCX must not be zero.  Unchanged
               on exit.

     Y         - COMPLEX array
               of DIMENSION at least ( 1 + ( m - 1 )*abs( INCY  )
               ).  On entry, the incremented array Y must contain
               the vector y.  Unchanged on exit.

     INCY      - INTEGER.
               On entry, INCY specifies  the  increment  for  the
               elements  of  Y. INCY must not be zero.  Unchanged
               on exit.
