WebBhas, thanks for the clarification about the Eigenvalues and the singular values. @Gregor, I cannot say I agree with your statement. The first document I attached states: 'If A is singular or ill-conditioned, then we can use SVD to approximate its inverse' Also, the wiki page states: 'A non-Hermitian matrix B can also be inverted using the following identity'. WebThe rank tells us a lot about the matrix. It is useful in letting us know if we have a chance of solving a system of linear equations: when the rank equals the number of variables we may be able to find a unique solution.
