Hi, we have a bug report in Cholesky implementation of Accelerate on the LAPACK GitHub. See: https://github.com/Reference-LAPACK/lapack/issues/1408 This is to let you know. This might be a user error but I thought I'd let you know. I did not try out for myself. Julien.
This might be related to a general bug in the apple implementation of diagonalization (zheev) that gets wrong eigenvectors in some specific cases. See test script below.
langou, m.w.h., Do see these problems if you opt in to the new LAPACK? See m.w.h.’s other thread for more about this.
Share and Enjoy
