WebMar 24, 2024 · An n×m matrix A^- is a 1-inverse of an m×n matrix A for which AA^-A=A. (1) The Moore-Penrose matrix inverse is a particular type of 1-inverse. A matrix … WebOnly square matrices are invertible. That is, if a matrix is invertible, then it is square. Remember that an nxm matrix is a function from ℝⁿ to ℝ^m. So a 3x2 matrix is a function from ℝ³ (3D space) to ℝ² (a plane). This will have to squish many vectors down into a smaller space, so we can't properly define an inverse.
