Does anyone know what this means?

Mess = not necessarily 0 but not easily expressible in terms of A11 and A22

Can you give a source on that? I couldn't find a more formal definition on Google.

it's an informal 'Mess', it's not mathematical terminology

i'm guessing this is some homework pdf and not a textbook?

Here's the book that it's from:

https://www.amazon.com/Matrices-Linear-Transformations-Second-Mathematics/dp/0486663280/ref=sr_1_1?ie=UTF8&qid=1488333155&sr=8-1&keywords=cullen+matrices+and+linear+transformations

pretty bad for a textbook then, but still it just means 'not easily expressible'

only obvious simplification is if A12=0 then you know Mess=0

is that loss?

Alright, thanks. I guess I shouldn't be trying to make something complicated out of something simple.

Ayyyyy you just reminded me that I should be studying for my linear algebra test tomorrow instead of shit posting on 4chan
