For theory problem 1, the solution says to compute the matrix U by computing u_j = X v_j. But for me, the question is, the matrix V is of dimension NN, so basically I can only compute N columns of the matrix U. But U is supposed to be a matrix of dimension DD and by assumption D >>N, so how can I compute the complete U?
how to compute the unitary matrix U?
