This book represents the first synthesis of the considerable body of new research into positive definite matrices. These matrices play the same role in noncommutative analysis as positive real numbers ...

Positive definite matrices play a central role in mathematics, physics, statistics and engineering due to their unique properties and widespread applicability. These matrices, which are characterised ...

Abstract: We state theoretical properties for k-means clustering of Symmetric Positive Definite (SPD) matrices, in a non-Euclidean space, that provides a natural and favourable representation of these ...

This repo contains 2 functions that do the same thing, one is a hand unrolled copy of the other. See my articles on my blog here and here for a more in-depth explanation. The TLDR is that since a 5x5 ...

ABSTRACT: We exploit the theory of reproducing kernels to deduce a matrix inequality for the inverse of the restriction of a positive definite Hermitian matrix.

Generating a 3 x 3 non-singular matrix with 3 non-zeroes Generated matrix: Real symmetric positive definite matrix, dimension 3x3 with 3 entries. 0: 9.9999E-01 1: -3.1031E-01 2: 3.9037E-01 This matrix ...
