 # simd_utils
 
 A header only library implementing common mathematical functions using SIMD intrinsics.
-This library is C/C++ compatible (tested with GCC7.5/9.3 and clang 9).

 Thanks to Julien Pommier and Giovanni Garberoglio for their work on sin,cos,log, and exp functions in SSE, AVX, and NEON intrinsics.
 Thanks to the DLTcollab team for their work on sse2neon.
