you know what really grinds my gears?

When people call an n dimensional array that only holds data and in no way represents a linear transformation, a matrix.

"In mathematics, a matrix is a rectangular array of numbers, symbols, or expressions. "

and you can add and multiply them. Does it really make sense to multiply images? Does it? Huh?

Adding and multiplying images is a standard feature of most image editors. Fireworks, Photoshop and (probably) the Gimp can all do it.

adding makes sense, but multiplying? What does the result look like, and what are the operations used for taking linear combinations of the colors in the image?

It makes sense to multiply an image by a transformation matrix (translating, rotating, scaling)

It makes sense to use multiplication for convolution effects (blurring, edge detection)

It makes sense to multiply two images' rgb values together (multiply blending in Photoshop)

ofc none of these examples are straight-up matrix multiplying two images together

Read SICP.

Technically they don't support either, because resulting values must be clamped.

Reported for sending SICP, enjoy your ban

could you explain how matrix multiplication plays in role in that, or provide a link? That sounds interesting.

you havent even watched the lectures, how did you get in here?
