2D FFT of Eigen matrices using FFTW library Jun 22, 2022 at 1:25pm JamieAl (236) I'm trying to use the FFTW library with Eigen. Since Eigen's unsupported module is slower. So, I'm struggling on implementing a very basic example. Here is what I have so far:...
We prove, using eigenmatrices, that if an operator commutes with an operator of finite rank, then it commutes with an operator of rank one.doi:10.1016/j.laa.2006.06.017Rubén A. Martínez-Avenda?oElsevier Inc.Linear Algebra and its Applications...
PROPERTIES OF EIGENVALUES AND EIGENVECTORS OF LARGE-DIMENSIONAL SAMPLE CORRELATION MATRICES Furthermore, we establish a theorem concerning CLT for the linear statistics of the eigen-vectors of large sample covariance matrices. This theorem improves... Y Yin,Y Ma - 《Annals of Applied Probability An ...

In this paper we analyze and solve eigenvalue programs, which consist of the task of minimizing a function subject to constraints on the “eigenvalues” of the decision variable. Here, by making use of the FTvN systems framework introduced by Gowda, we interpret “eigenvalues” in a broad fas...
