WebFeb 6, 2024 · Direct Linear Transform. We want to obtain the non-trivial solution of an equation of the form A x = 0. In the real world, there can be some noise, so we write the equation as A x = w, and we solve for x such that w is minimized. The first step is to determine the SVD decomposition of A. Our goal is to minimize w for some x.
