Inverse of non-square matrix - Mathematics Stack Exchange
2015年1月10日 · Finally, if the matrix is non-square, the number of independent rows or columns is at most the smaller of the number of rows and number of cols, hence one set or the other is not independent, so either a left or right inverse can't exist.

linear algebra - shortcut for finding a inverse of matrix
I need tricks or shortcuts to find the inverse of $2 \\times 2$ and $3 \\times 3$ matrices. I have to take a time-based exam, in which I have to find the inverse of square matrices.
matrices - Transpose of inverse vs inverse of transpose
Given a square matrix, is the transpose of the inverse equal to the inverse of the transpose? $$ (A^{-1})^T = (A^T)^{-1} $$
Why is only a square matrix invertible? - Mathematics Stack …
That a matrix is invertible means the map it represents is invertible, which means it is an isomorphism between linear spaces, and we know this is possible iff the linear spaces' dimensions are the same, and from here $\,n=m\,$ and the matrix is a square one.
Determining the left inverse of a non-square matrix
I understand that non-square matrices do not have an inverse, that is, both a left inverse and a right inverse. Yet, I am fairly certain that it is possible for a non-square matrix to have either a left inverse or (exclusively) right inverse. Take the example where, I want to …
