What is Julia's approach to linear algebra performance optimization?

Julia uses highly optimized BLAS/LAPACK libraries with automatic memory and SIMD optimizations.

Linear algebra operations in Julia are delegated to optimized native libraries like OpenBLAS, MKL, or BLIS. Julia ensures data is stored in contiguous column-major format, allowing these libraries to operate efficiently. The compiler also fuses operations where possible and avoids unnecessary allocations.
