<summary>DirectXMath is an all inline SIMD C++ linear algebra library for use in games and graphics apps.</summary>
<description>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 through SSE2 and ARM-NEON intrinsics support in the Visual Studio compiler.</description>
