times a scalar. We call the columns of U the left singular vectors, and the columns of V the right singular vectors. Finding V and U To find V, we calculate AᵀA (U can be found in a similar manner, using AAᵀ). AᵀA is a symmetric positive semidefinite matrix. Using the Spectral Theorem, we know that
