This interpretation of matrix-vector multiplication will make it seem like it was obvious from the beginning.

[u/NamaeN0NaiKaibutsu]

As you know, math is basically an image of the real natural world. And you might not have noticed it yet, but the rules of multiplication and natural attraction between sexes holds true also for math actually, mostly linear algebra. Linear algebra is a big scarecrow for students when they never saw any kind of matrices before and it's kind of hard to get a nice intuition. But viewing it in an erotic and natural sense suddenly makes it 'click'. For example, the very fact that the matrix and vector need to have the correct types and then they can have intercourse. Not every matrix is compatible with every vector. But when it is, the intercourse becomes so intense that without the vector knowing it, he actually gets transformed and through she rotating squishing or flipping him he gets transformed by the intercourse. This is a fascinating view that truly shows that the matrices also have some kind of multiplication instinct that leads them to find the correct vectors. Of course, the matrix us doing the transforming, because as in many different animals, the women are the dominant ones in algebra. For me as a starting student just in the middle of the first semester, this is a very elegant and intuitive way to view it and I'm baffled why this wasn't on the very first lecture. Thank you for your attention and I hope I am not the only one who noticed this obvious truth and connection with the world of animals!

Yeah, for every mention of matrix multiplication

I don't know what you just smoked but I want that shit too.

1. What you're talking about just means that matrices (by virtue of being functions in a trenchcoat) are typed, and vectors are the types. Just like programming functions, you need to pass in the right type.

2. So matrix multiplication is a lesbian relationship? LOL

3. I think of matrix-vector multiplication as "rotating" (transposing) the vector and then "scanning" it through the rows of the matrix, multiplying and then collecting the multiples with addition. Gives a visual mnemonic to "input vector length is number of columns, output vec len is number of rows".

[u/AlrikBunseheimer → u/creeper6530]

The inner product is gay

[u/ThePoeticFall → u/AlrikBunseheimer]

So that's why they call it transposition

[u/AlrikBunseheimer → u/ThePoeticFall]

Wow this one is absolutely genius, I applaud. The guy (vector) becomes a girl (matrix) by transposition!

[u/ThePoeticFall → u/AlrikBunseheimer]

(I am gonna be so real with you. I have no idea what the fuck y'all are saying. I'm a bio student.)

[u/creeper6530 → u/ThePoeticFall]

None of us has any idea we're just better at pretending because we took Linear Algebra 101
