- It can range from being a Non-Invertible Non-Square Matrix to being either a Left Invertible Non-Square Matrix (with a left inverse to being a Right-Invertible Non-Square Matrix (with a right inverse).
- It can range from being an Abstract Non-Square Matrix to being a Non-Square Matrix Structure (such as a non-square array).

- … Non-square matrices (m-by-n matrices for which m ≠ n) do not have an inverse. However, in some cases such a matrix may have a left inverse or right inverse. If A is m-by-n and the rank of A is equal to n, then A has a left inverse: an n-by-m matrix B such that BA = I. If A has rank m, then it has a right inverse: an n-by-m matrix B such that AB = I.
