1. Regarding the eigenvectors of symmetric, it is correct to say the eigen vectors are orthogonal if the matrix is full rank. However, the formal definition is there always exist a orthornormal basis which contains the eigen vectors of the symmetric matrix, for details refer to • 25. Symmetric Matrices... , where professor Strang explains the case with eigen vectors with eigen value of 0.
2. When S_L or S_R right has eigen values of multiplicity more than 1, there is an entire subspace of them, therefore, we need to put an orthonormal basis of the subspace to sure all the eigen vectors are perpendicular. Of course, this is already getting more involved with the details with the derivation of the SVD formula in the first place, I think I will leave this to the expert: • 6. Singular Value Deco...
