BLAS Library (libblas.a)

COMPLEX FUNCTION CDOTU(N, X, INCX, Y, INCY)
INTEGER INCX, INCY, N
COMPLEX X(*), Y(*)

DOUBLE COMPLEX FUNCTION ZDOTU(N, X, INCX, Y, INCY)
INTEGER INCX, INCY, N
COMPLEX*16 X(*), Y(*)

The CDOTU or ZDOTU function returns the complex dot product of two vectors.

N	On entry, N specifies the number of elements in X and Y; unchanged on exit.
X	Vector of dimension at least (1 + (N-1) * abs(INCX) ); unchanged on exit.
INCX	On entry, INCX specifies the increment for the elements of X; unchanged on exit.
Y	Vector of dimension at least (1 + (N-1) * abs(INCY) ); unchanged on exit.
INCY	On entry, INCY specifies the increment for the elements of Y; unchanged on exit.

For values of N <= 0, a value of 0 is returned.
