我正在做一些性能分析，我想知道，当数据类型已知(双精度)时，numpy是否会对其标准数组操作进行矢量化.
a, b = (some numpy arrays)
c = a + b #Is this vectorized?

是的.

* This file is for the definitions of simd vectorized operations.

* Currently contains sse2 functions that are built on amd64, x32 or
* non-generic builds (CFLAGS=-march=...)
* In future it may contain other instruction sets like AVX or NEON detected
* at runtime in which case it needs to be included indirectly via a file
* compiled with special options (or use gcc target attributes) so the binary
