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.
