What is a Hadamard (Matrix) Product?

Hadamard Product is obtained by taking two matrices of the same dimension (n x n) to produce another matrix of the same dimension where each element of the new matrix is the product of corresponding elements of the two matrices.

Here is how the new Hadamard product is calculated.

Using R you can calculate Hadamard product as shown.

Here are the two matrices.
