WebInverse of a Matrix We write A-1 instead of 1 A because we don't divide by a matrix! And there are other similarities: When we multiply a number by its reciprocal we get 1: 8 × 1 8 = 1 When we multiply a matrix by its inverse we get the Identity Matrix (which is like "1" for matrices): A × A -1 = I Same thing when the inverse comes first: Web11 jan. 2024 · Learn more about matrix array, matlab .
