This provides an element-level rather than row-level focus, which I feel is
more appropriate.
One could draw lines to connect each of the elements, but that'd likely be
too noisy and it'd be a lot of work.
This starts with the Hadamard Product as an example. It also:
- Configures BibLaTeX with biber.
- Renames \undef, since BibLaTeX apparently defines it.
- Redefines the citation and url colors, since they're bright and ugly.
This is just some plain English to go along with and help rationalize the
text. Further rationale will be provided in a dedicated section in the
future; such information is vitally important to understand why the system
evolved as it did.
I find this provides a visualization that is likely to be significantly more
intuitive for others. It even holds when the matrix is not
rectangular (yes, I know, it's not really a matrix then), so long as all
matrices share the same respective K_j.
This uses the same variable subscript on \equiv itself to define the symbol,
rather than the previous symbol which looked like equiv rotated, but also
looked too much like a turnstile used for "infer", a metalanguage construct
that is not appropriate here. It kept bothering me.
I removed this when I added concmath, thinking that it would include it for
me, and apparently I never re-added it after realizing that it didn't.
I'm a big fan of the typography of Concrete Mathematics.
The subscript of the matrix family adds too much vertical space. This
offsets that to restore it to about what it otherwise would be, since the
second subscript does not get in the way.
This was originally going to be used to define @yields for the classifier,
but I took a very different approach which doesn't require reasoning about
the system in terms of recursion.
This defines @as and @yields, but does not yet define matches formally.
It's also missing index entries, which I'll take the time to add after I'm
sure things are staying as they are.
This was quite a bit of work, and the approach I took is different than I
originally expected, so Section 0 can use some cleanup.
There is more to come from here.
This is going to evolve a great deal, and note that the yield definition is
completely absent.
It may be time to switch to natural deduction (Gentzen-style).
That macro previously expanded into \Classify, but that was undone before
committing to make it clear when one is referring to a variable vs. a
classification as a definition.
