You know how you can write “5+5+5-4-4-4” as “35-34”, and then use it for weird shortcuts like “3*(5-4)”? Well, matrices make for relatively easy handling of certain systems of equations, letting you fiddle with the whole system at once instead of restating equations one by one.

Aqarius@lemmy.worldto Out of the loop@lemmy.world•Can someone explain to me what is going on with Bluesky?27·1 month agoThe pro move would have been to spin up a mastodon instance and then star an electric car company.
But even then, the twist was that even if the monster is real, the bad guys were still mundane crooks.
Also, how yhe hell does the Akashic record have no matches? Shouldn’t it at least return the query itself?
No, I mean the OP. Theirs is a half-crossover.
I was about to say - the outs go in, and the ins go out. The picture is wrong.
It started off as sincere, but the minute it launched Poe’s law ate it.
And would be correct. But if we’re planning a health system, and I keep insisting on bandaids but refuse to even talk about anything else, my proposal is a bait-and-switch. That’s the problem, not UBI/NIT, as a concept.
That’s under the assumption that you’re actually getting them to a doctor and not just slapping the bandaid on and calling it a day.
Seems more like something Diogenes would pull.
The usual translation is “political power grows out of the barrel of a gun.” It’s a Mao Zedong quote.
Cold blood usually just means as opposed to “hot blood”, that is, in the heat of the moment. People say it as if it makes it particularly bad, but really, it’s almost a synonym for “premeditated”.
Do you and Mork keep in touch?
Same with Mazovism, it incentivizes you to act like a jackass for very little payoff. It’s great design.
Now I’m imaging him clock out, go home, and put on a suit and tie as he heads to a dinner party.
That last line was waiting around the corner with a 2x4
Yeah, only notification notification I ever see is when I send tabs from my PC.
Essentially.
A straightforward example would be an equation system: 2x+4y=10, 3x+5y=13. You could solve it manually, or you could call Cramer’s rule and plug the numbers into the formula:
Ax+By=C
Dx+Ey=F
x=[CB/FE]/[AB/DE] = (CE-BF)/(AE-BD)=(10*5-4*13) / (2*5 - 3*4) = (50-52)/(10-12)=1,
y=[AC/DF]/[AB/DE]=AF-CD / AE-BD = -4/-2=2
Pure algo, no thinking required. Also note that you don’t strictly need x to get y and vice versa.
In a more complex example: You’re making a program to draw something in 2D. You could implement mirroring, rotation, scaling etc…, or, you could declare each point (xy) a vector V=[X Y], implement matrices, and then V times [1 0/0 1] gives you V, [-1 0/0 1] gives you V mirrored on the Y axis, [1 0/0 -1] mirrors on the X axis, [j 0/0 j] scales it by j, [cosw -sinw/sinw cosw] rotates it by w… Makes life much easier.
