Hadamard Product: Defined Operation
It needs to be noted that the operation of Hadamard product is defined only when both matrices have the same number of rows and the same number of columns.
This restriction applies to the operation of matrix entrywise addition, which can be considered as a specific application of the Hadamard product.
