Looking for a to code the Hadamard product without using a library. Still relatively new to Elixir so feeling a bit lost.

For the non mathematicians like me, here’s the wikipedia definition

In mathematics, the Hadamard product (also known as the element-wise product , entrywise product [1]: ch. 5 or Schur product [2]) is a binary operation that takes two matrices of the same dimensions and produces another matrix of the same dimension as the operands, where each element i, j is the product of elements i, j of the original two matrices.

:grimacing:

I’d start with how to represent the input matrices and make sure they have equal dimensions … :face_with_hand_over_mouth:

Enum.zip_with(a, b, &*/2), but this will work only on 1D lists.

I was joking of course :slight_smile: But was pointing towards some sort of multiplying two 1D lists
