WebA matrix X g is a generalized inverse of the matrix A if and only if it satisfies A X g A = A. So, using the definition of a generalized inverse, we can write a solution to the least squares equation as β = ( X T X) g X T Y Share Cite Improve this answer Follow answered Sep 7, 2013 at 18:30 user25658 1 WebSolution We will find a matrix representing and show that does not exist. Since invertibility is preserved by similarity, we may use any representing matrix to determine invertibility. We use the standard matrix since it is easiest to compute. We have so the matrix is Note that is antisymmetric. Now , so does not exist. Therefore is not invertible.
