Purpose

The DirectXMath API provides SIMD-friendly C++ types and functions for common linear algebra and graphics math operations common to DirectX applications. The library provides optimized versions for Windows 32-bit (x86), Windows 64-bit (x64), and Windows on ARM/ARM64 through SSE, AVX, and ARM-NEON intrinsics support in the Visual C++ compiler.

For developers new to DirectXMath, you may want to consider using the SimpleMath wrapper in the DirectX Tool Kit for DirectX 11 / DirectX12 as a starting point.
