comment How to estimate the matrix condition number in the 2-Norm?
You can compute it yourself with Norm[mat,2]Norm[Inverse@mat,2], but this is unsatisfying...

It's cool that functions like ^ work on the association's values.

Neat. The really interesting part of this isn't that adding a key replaces an existing one, but that you can merge by putting the whole association inside another like <|#, ...|>.

comment How is OptionsPattern[] defined? Can I replicate this?
Thanks for the answer. Why did you use pt and b and not pt_ and b_? I was under the impression that pt : ptrn would just specify a default value; is something else happening here?

I don't really want Options — specifying -> rules for each argument will be even messier than the current definition using named patterns like var_. I just want a way to decrease the number of times I have the whole argument list written out.
