Programming puzzles: processing lists!

Yes arrays and matrices would be pretty powerful if, somehow, their processing would cost similarly to list (or having the same amount of helpful list commands. For example there is no sigma row or sigma array, while there is sigma list to get the sum of the numbers). Instead at times they are slow, especially with large matrices.

Or maybe I am influenced by past experiences. I didn't touch matrices for a while.

I was thinking more of things like matrix multiplication (vs. Hadamard product), creating constant arrays, identities, etc. The commands can simplify the coding, even if the processing isn't as speedy. I suppose it depends entirely on the processing that is needed.
