What is the clearest way to refer to -10 in the example vector v; v = (1, ⅔, -10)? I initially was going to refer to it as the largest entry of v but don't want to run the risk of having the reader infer that I'm implying 1 (obviously, in this paragraph I'm talking about the 'largest' of a non-specific vector, so I can't refer to it as the third entry).
Here is the context:
[…] we use the convention of flipping the sign of Pq so that it's largest unsigned entry is always positive.
Pq is a matrix with many entries (some positive, some negative). It turns out that the only the magnitude of these entries matter in this application. Still, to compare two such matrices (say Pq and Pqʹ), we need to impose a sign convention.
