WebAn identity matrix is capable of multiplying any matrix with any order (dimensions) as long as it follows the next rules: If in the multiplication, the identity matrix is the first factor, then the identity matrix must have dimensions with as many columns as the matrix it is multiplying has rows. 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. We get
