Linear algebra is high school math, no? It is in my country at least.

  And for how many years after high school do you confidently remember how to invert a matrix? For me personally, that number is smaller than the number of years I’ve been out of high school.

    I get a thrill when I get to do a math-class math thing in programming. It’s rare. It’s happened with linear algebra once. That one time was about ten years ago, was very simple, and occupied perhaps an hour total of my time, at most. At this point I’d have to google to be 100% sure I even know what it means to invert a matrix. ... but I remember it being super simple and I’d probably be in the “just write it” camp.

    Not even one year, if it is about niche knowledge that require accuracy. Schools don't teach formulas. That's the misunderstanding of a student that only sees the next exam. Schools teach you where to look when you don't have the answer.

    Yeah, but at least I heard about it, a quick refresher should be enough, it’s not an alien concept. And a good programmer should be able to learn a new domain if they want to excel in the craft, otherwise we’re back to software factories and code monkeys.

  It's not taught at most high schools schools in California.

  Is there a JQuery Linear Algebra routine?
