DESCRIPTION
     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.
