hlsl-style linear algebra library

• bool (b16 b32 b64)、half [1]、float、double、short、ushort、int、uint、long、ulong、decimal [2]
• Vector2~4 (float3 double4 int2 ...)
• Matrix2x2~4x4 (float3x3 double4x2 int2x3 ...)
• Hlsl-like cartesian product swizzle (.yzx .abgr ...)
• Full simd support
• Simd accelerated [3] log, exp, pow, fmod, trigonometry

[!NOTE] <a name="note-1"></a>

1. Very slow on CPU <a name="note-2"></a>
2. Cpu only <a name="note-3"></a>
3. Lower precision than C# system library

Function ULPs (vs C# system library)

| function | float | double | |----------|-------|--------| | log2 | 1 | 1 | | asin | 2 | 2 | | acos | 2 | 2 | | atan | 2 | 2 | | atan2 | 2 | 2 |

• The function that needs to be rewritten due to insufficient precision is not in the table

Todo

• [ ] tests
• [ ] rewrite the function with too low precision
