Solution Summary

The expert calculate the singular values in this case.The eigenvalues of A are all proved.

Solution Preview

(a) The spectral theorem can be applied to obtain unitary diagonalization of A = UΛU * . Therefore,

sqrt{A*A} = U |Λ| U*

and so the singular values are simply the absolute values of the ...
