4.21. The pixel values for different images are given in Table 4.18 (they each contain 4 pixels). Select one of them and then answer the questions that follow. (a) What is the SVD of the corresponding matrix? (b) Find W₁ and W2, as defined in (4.49). (c) Suppose the approximation A≈ A₁ is used, where A₁ = 01 W₁. Find A₁, and determine the relative error is using this matrix to approximate A.
