Remarks
Except for the main diagonal, whose elements are all ones, the identity matrix is a square matrix composed of zeros. Unlike all other matrix multiplications, the multiplication between an identity matrix and another matrix is commutative.
This is useful for initializing a matrix to a known value before you perform additional operations, such as a transformation.
