Eigen

Eigen excels as a swift and highly compatible C++ library for linear algebra, optimized for speed without sacrificing functionality. It leverages expression templates and lazy evaluation to minimize runtime overhead, enabling rapid execution of matrix and vector operations. Its broad compatibility extends to integration with popular frameworks and hardware, supporting everything from embedded systems to high-performance clusters. Ideal for real-time applications and performance-critical code, Eigen helps developers achieve faster results while maintaining code portability and ease of use across different development environments.
