RustyCookie1425185dI got it when I started to visualise it.
Jupyter is a great tool for this.
HiFiWiFiSciFi4097184dIt’s like arrays of arrays.
kiki17747184dBruh it’s the easiest topic. You just kinda do things in parallel, sometimes just treat basic operations like functions, even more like overridden methods
neeno3357184d@electrineer this. 3blue1brown is awesome, I basically learned calculus from his videos instead of my teacher. I hate how teachers just say "here's the formula, off you go" like no, that's not how it works. You have to understand why and how it works, not just accept stuff as a fact and be done with it.
Fast-Nop33444184dWhy, that's easy. If an NxN matrix as linear transformation puts some vectors upon themselves, that's the eigenvectors. They can be longer or shorter than originally, and the proportionality factor is the eigenvalue.
If you have a large spread between the eigenvalues, that leads to numerical instability with computer solvers, which is a bad condition.
gibus451184dConcepts are only easy when they click. If you're struggling with a concept your lecturer provides, you should find other resources that explain it in different ways. 3B1B is very good, khan academy will have the topic as well.
dmonkey1762184dAs other people said, look for 3blue1brown's videos.
In my experience many professors and books don't give you the right point of view on this topic. This guy does.
