Complex cdotu( n, x, incx, y, incy )
Integer incx, incy, n;
Complex (*x)[ n ], (*y)[ n ];
ddot, sdot, zdotc, and cdotc compute the dot product of vector x and
vector y.
dot <--- transpose( x ) . y
zdotu, and cdotu compute the hermitian dot product of vector x and vector
y.
dot <--- transpose( conjg( x ) ) . y
incx and incy specify the increment between two consecutive elements of
respectively vector x and y.
