Sampling Pfaffian point processes and the symplectic Arnoldi method

Alan Edelman, Sungwoo Jeong, Simeon Schaub

We present an exact sampling algorithm for Pfaffian point processes based on a skew-symmetric analogue of the Cholesky factorization. This algorithm enables efficient sampling of a…

On the structure of the solutions to the matrix equation $G^{*} J G = J$

Alan Edelman, Sungwoo Jeong

We study the mathematical structure of the solution set (and its tangent space) to the matrix equation $G^{*} J G = J$ for a given square matrix $J$ . In the language of pure mathematics,…

Fifty Three Matrix Factorizations: A systematic approach

Alan Edelman, Sungwoo Jeong

The success of matrix factorizations such as the singular value decomposition (SVD) has motivated the search for even more factorizations. We catalog 53 matrix factorizations, most…
