Roundoff Patterns from Triple Kronecker Products
While I was working on my posts about Pejorative Manifolds, I was pleased to discover the intriguing patterns created by the roundoff error in the computed eigenvalues of triple Kronecker products. ContentsKronecker ProductExampleEigenvalues with high mu…

This is what happens when two logarithmic spirals love each other very much.
