If A is invertible then an inverse of A does not need to be unique.Square Matrix and Invertibility:There is a connection between the order of a matrix and its invertibility. Inverses are not defined for non-square matrices. However, this doesn't mean that all square ...
A necessary and sufficient condition for a dual matrix to have a {1}-dual generalized inverse is obtained. It is shown that a dual matrix always has a {1}-, {1,3}-, {1,4}-, {1,2,3}-, {1,2,4}-dual generalized inverse if and only if it has a {1}-dual genera...

12. Finding the characteristic polynomial of a Matrix ParserNG allows the quick evaluation of the characteristic polynomial of a square matrix; this polynomial can then be solved to find the eigenvalues, and hence the eigenvector of the Matrix. ...
By 'does not exist' we mean that the original matrix XTXXTX is not invertible, i.e. its inverse (XTX)−1(XTX)−1 does not exist. Usually this relates to the presence of eigenvalues with extremely small magnitude (or zero) in the matrix XTXXTX. This issue of non-invertabilty sug...
