Given vectors u and v, the vector direct product, also known as a dyadic, is u v congruent u⊗v^T, where ⊗ is the Kronecker product and v^T is the matrix transpose. For the direct product of two 3-vectors, u v = [u_1 v^T u_2 v^T u_3 v^T] = [u_1 v_1 | u_1 v_2 | u_1 v_3 u_2 v_1 | u_2 v_2 | u_2 v_3 u_3 v_1 | u_3 v_2 | u_3 v_3]. Note that if u = (x_i)^^, then u_j = δ_(i j), where δ_(i j) is the Kronecker delta.
We guarantee you’ll find the right tutor, or we’ll cover the first hour of your lesson.
Club Z! has connected me with a tutor through their online platform! This was exactly the one-on-one attention I needed for my math exam. I was very pleased with the sessions and ClubZ’s online tutoring interface.
My son was suffering from low confidence in his educational abilities. I was in need of help and quick. Club Z! assigned Charlotte (our tutor) and we love her! My son’s grades went from D’s to A’s and B’s.
I’ve been using Club Z’s online classrooms to receive some help and tutoring for 2 of my college classes. I must say that I am very impressed by the functionality and ease of use of their online App. Working online with my tutor has been a piece of cake. Thanks Z.
Jonathan is doing really well in all of his classes this semester, 5 A’s & 2 B’s (he has a computer essentials class instead of PLC). In his Algebra class that Nathan is helping him with he has an A+.
Sarah is very positive, enthusiastic and encourages my daughter to do better each time she comes. My daughter’s grade has improved, we are very grateful for Sarah and that she is tutoring our daughter. Way to go ClubZ!
