Random C++ Part 1: Building a block sparse matrix in Eigen

This article provides a detailed, technical tutorial on constructing a 2x2 block sparse matrix in C++ with the Eigen library. It explains the importance of column-major storage for performance, outlines the implementation steps using Compressed Column Storage, and discusses the challenges of integrating sparse and dense matrix blocks within the Stan computational framework.
