> I'm also going to have to strongly disagree with you in regards to Euler's proofs. Analysis as a discipline is far more mature than it was in Euler's time, but Euler still clearly proved the things we attribute to him. I

Over the years I've audited a lot of math classes and tried various ways of taking notes. I've found that live-TeXing lets me keep half my attention at best on the lecture. The people I've talked to about it agree. Also, when

Thanks! It doesn't explain Gallager codes since I don't know much about them (but will look into them now!). It only briefly mentions RS decoding, since the RS erasure code uses Vandermonde matrices, and Cauchy matrices seem more

> If you try to define a vector space over a set without multiplicative closure, the vector space cannot be closed under scalar multiplication. Among other things, linear combinations stop being invertible (or even possible in general),

Cool, what does the conversion look like? Do you have a reference?

My “foolproof” comment was based on Vandermonde matrices not always being invertible during decoding without an extra step, which tripped up multiple implementations. (PAR1 suffered from this problem, then they tried to fix it with PAR2 but

I prefer to think about it as there are three special types of numbers: zero, units (invertible elements), and prime numbers, which exclude zero and units. In the integers, the units are +/-1, so that’s why they are not prime. In the r

The coordinate-free concept behind transposes is the adjoint, which shows up in multiple places in mathematics. Basically, you have a formula: <Ax, y> = <x, By> where <,> is some inner product, and you say that the the lin
