Hadamard product (matrices) - Wikipedia
https://en.wikipedia.org/wiki/Hadamard_product_(matrices)
In mathematics, the Hadamard product (also known as the element-wise product, entrywise product or Schur product ) 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. It is to be distinguished from the more common matrix product. It i…
