comment Uniqueness of Singular Values
Thanks, I forgotten the possible rectangularness of $U$s...

Ok, so we would have used $\hat{U}=M^T U M$, IF we did select the same basis for the domain, but here we are selecting two different bases on the very purpose. Thank you again, perfectly clear!

Many thanks again.

And why $\hat{U}=UM$ and not $\hat{U}=M^T UM$? After all, $\hat{U}$ and $U$ should be similar via the orthogonal change of basis operated by $M$..

Very clear and detailed, thanks. With $\rho(-)$ you are indicating the spectral radus?

Thanks. I'm in a struggle about what answer to accept. Pavel gave a bit more detailed explanation, but you answered first.

comment Mysterious Proof about Induced Norms (was: Uniqueness of SVD)
@Markus: I suppose what Ewan Delanoy exposed in his post is essentially taken for granted by Trefethen. Probably a "give details of the proof" approach. Or at least I hope so.
