Let $ k|n$ and $ k\geq 2$ and consider $ k$ symmetric matrices $ $ A,B,\ldots,K \in \mathbb{R}^{n\times n}.$ $ Consider a $ k-$ interleaving of these matrices where we take every $ k^{th}$ row in order from the given matrices. I will illustrate with an example for $ k=2.$ Let $ $ A=\begin{bmatrix} a_0&Read more
