[5] These … WebFeb 22, 2024 · 1. The answer is no. You can have an inverse on one side, but not on both. The main reason is rank (which is the dimension of the image). If A and B are two matrices that can be multiplied together, rank ( A B) ≤ min ( rank ( A), rank ( B)). So if A is an n × k matrix and B is a k × n matrix, then rank ( A B) and rank ( B A) are at most min ... WebSo we can and should ask the question, whether there may be an A − 1 with A A − 1 = I m and A − 1 A = I n, if n ≠ m. The answer is no: The matrix A corresponds to a linear map f: R n → R m, x ↦ A x. By the dimension formula we have: n = dim ( ker f) + dim ( im f). If A has an inverse, then so does f ( y ↦ A − 1 y ). rpm auto newberry fl
