Web28 sept. 2024 · Yes, this is why it is called the identity matrix. Any matrix multiplied by the identity matrix is the original matrix, just as the multiplicative identity for R is 1. For an m × n matrix A, we have ( A I) i j = A i 1 I 1 j + A i 2 I 2 j + ⋯ + A i n I n j But I i j = 0 when i ≠ j and 1 otherwise. So ( A I) i j = A i j.
