WebA matrix is positive definite if it's symmetric and all its eigenvalues are positive. The thing is, there are a lot of other equivalent ways to define a positive definite matrix. One equivalent definition can be derived using the fact that for a symmetric matrix the signs of the pivots are the signs of the eigenvalues. WebAug 28, 2016 · Repeated eigenvalues do have a connection to problems diagonalizing a matrix, though. In the case of I the solution is clear, but can we approach the case of A ′ A with repeated eigenvalues from first principles, and without having to resort to I? – Antoni Parellada Aug 28, 2016 at 14:31
