Hey guys, this is a quick introductory video to what an eigenvector is and how it relates to eigenvalues. It'll be used a lot later on, so it's good to know!
Outside of that, I'm going to try to be way more consistent with my video uploads. It's been forever since my last one and there are reasons for that, but they are not worth mentioning here.
All of the simulations done on this channel can be seen live on:
/ leioslabs
Or after the fact on:
/ @leioslabslive
Which is my second channel for streams and stuff. I've got a bit of a backlog of videos to make, so hopefully everything goes smoothly from here on out!
I am now way more active on twitter, too, so feel free to follow me there (no pressure):
/ leiosos
Outside of that, the background music is from Josh Woodward (sped up 1.5 times). He's a super cool guy, so go check out his stuff, if you can:
www.joshwoodward.com/
I think that's all for now, so have a great day, night, afternoon, morning... whatever time it happens to be your time and I'll see you next time!
NOTE: In the visualization of eigenvectors, I plotted only vectors that passed through the origin on (0,0,0), this does not need to be the case! So long as the points are in the right direction, you will have the right vector and you will see only stretching!

The reason why professors who teach just from the book are doing a disservice to their students. I had a friend who took linear algebra with me and after two semesters still asked me 'what is a vector space. The problem issued when the prof never expanded beyond the book. He couldn't be bothered to bring in new material into the class.

It's very common to miss the point on eigenvectors, the main reason is because you need to understand what differential equations are for, how these can help solving them and how linear algebra is in fact divided into 2 parts, one for solving normal equiations Ax=b and one for solving differential equations Ax=λx. All of this makes sense much later so it's a hard topic to bring enthusiasm.

In 4 min, I just learned what an eigenvector is. Why did my teacher take 3 hours to teach us this? and why didn't I learn anything in those 3 hours!? Great explanation! So, it seems that eigenvectors can only be used on linear vectors, since the line can only be stretched and not moved around, right? So, what about those points and lines that move around...what are those called?
@LeiosLabs
@LeiosLabs 8 жыл бұрын
To be clear, we are transforming individual points and depicting the vectors as lines between them. We could have had the eigenvectors anywhere else on the plane, it just made sense to have them all go through the origin for visualization purposes. The ones that moved are just ordinary vectors (I don't think they have a special name). Any vector that is not an eigenvector will move around in a similar manner. I hope it helped!

Cool! According to my understanding, matrix, in certain circumstance, can be treated as a selection mechanism. When you apply the multiplication between specific matrix, for example, A, and vectors in different directions, some of the vectors will show a specific property, under which they only change in magnitude without swaying from their original direction(including the opposite way). These vectors are known as the "Eigenvector".
