Webb15 apr. 2024 · The Kruskal rank of A is denoted by k A. Since the rank of a nonzero matrix A is the largest integer r such that some list of r distinct columns of A is linearly independent, we always have k A ≤ rank A. For example, the rank-2 positive semidefinite matrices in (1) have respective Kruskal ranks 2 and 1.
