 Sep30 awarded Explainer Sep7 awarded Yearling Jul2 awarded Curious Jun12 awarded Popular Question Jan12 awarded Nice Answer Dec10 comment simple question on SVD Sorry I should've been more clear - I was referring to the norm of the vector (which measures length) rather than the number of elements. You've figured out the solution I was suggesting yourself though! Dec10 comment simple question on SVD Why not compare the length of the $v_{old}$ and $v$? Should be cheaper than SVD. Or am I missing something?

Perhaps not in the first explanation of an equation, but if you have to say it many times, that's what I default to. Particularly reading/taking about anything in continuous time finance, $e^{-rT}$ quickly becomes 'ee minus arr tee' for me. Sep23 awarded Nice Answer Sep23 answered How is $e^x$ read aloud?
