C++ and Linear Algebra
summary
Proposes adding concrete matrix and vector types and infix operators to the C++ standard (proposal P1385), reusing mdspan for static vs dynamic matrix storage engines and offering layout, allocator and operation-trait customization; demonstrates solving a 2×2 linear system by matrix inverse, discusses BLAS, Eigen and Blaze interop and tradeoffs for fixed-size SIMD-optimized game code (SSE/AVX), and highlights practical bugs from sRGB non-linear interpolation that cause posterization and widespread wrong behavior in many engines.
