Web7.1. Bases and Matrices in the SVD 383 Example 2 If A = xyT (rank 1) with unit vectorsx and y, what is the SVD of A? Solution The reduced SVD in (2) is exactly xyT, with rank r = 1.It has u1 = x and v1 = y andσ1 = 1. For the full SVD, complete u1 = x to an orthonormal basis of u’ s, and complete v1 = y to an orthonormalbasis of v’s. No newσ’s, onlyσ1 = 1.
