A positive (semi-)definite matrix is a square matrix with the following property: (1.63)x′Ax=x′12(A+A′)x≥0,∀x. If the inequality is strictly greater, it is positive definite, otherwise positive semi-definite. From the definition, we can see that A is positive (semi-)definite...
Matrix approximationWe consider the manifold of positive definite matrices endowed with the Fisher Riemannian metric and some other distances commonly used in information theory. We show that for each of them the best approximant to A from the unitary orbit of another matrix B commutes with A....
In this paper, we consider the problem of optimal estimation of a time-varying positive definite matrix from a collection of noisy measurements. We assume that this positive definite matrix evolves according to an unknown GARCH (generalized auto-regressive conditional heteroskedasticity) model whose ...

The test failure in https://buildkite.com/julialang/linearalgebra-dot-jl/builds/330#01954c88-5de5-42fb-a0b4-e10f487d934e is because the matrix is not positive-definite. Since we construct the matri...
Hi, I could potentially be overlooking something simple here, but I think I'm hitting a rare edge case in torch.potrf. I've temporarily uploaded a 100x100 Tensor here that is positive definite. Numpy can compute the Cholesky on it, but T...
