1999 — Index Of The Matrix

Procedure to compute index via Smith normal form:

In the grand ledger of late-20th-century artifacts, few phrases invite as much puzzled curiosity as “index of the matrix 1999.” It sounds at once bureaucratic and mythic — an entry in a catalog, a codename for a project, an esoteric mathematical invariant, or perhaps a cultural cipher. To write about it is to use the term as both anchor and mirror: an anchor to investigate specific technical and historical senses of “index” and “matrix,” and a mirror to reflect on how we assign significance to numbers, dates, and labels. index of the matrix 1999

Theoretically, reduce (A) to JCF; the index is the size of the largest zero-eigenvalue block. Numerically, JCF is unstable under perturbations. Procedure to compute index via Smith normal form:
