| Apr 4, 2022 at 2:42 | comment | added | kale hops | yea, my mistake, each circle in my drawing is supposed to mean one scalar product of one component of the vector by one basis vector of the matrix, so the final vector is a sum of all those scalar products. | |
| Apr 4, 2022 at 2:38 | comment | added | DMGregory♦ | These interpretations are equivalent, but then the circles around your output vector should encompass the whole vector, not just one component, since each basis vector contributes to all four components. | |
| Apr 4, 2022 at 2:33 | comment | added | kale hops | I think of matrix multiplication as a linear combination of basis vectors, where the vector being transformed is an array of weights. Sums of dot products are confusing to me, so thats the source of my confusion. | |
