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 function 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.
