先装了matlab2018b，发现很频繁的crash，同时考虑到要跑的代码在>=2017a时就计算错误，于是转战matlab2016b
matlab2016b安装后，执行mex -setup报错：
>> mex -setup
find: 37589: No such file or directory
find: 37592: No such file or directory
find: 37595: No such file or directory
尝试了matlab2015b，发现mex依然报错，通过修改/path/to/matlab/bin/mexopts.sh中macos的sdk版本，以及clang_maci64.xml中macos sdk版本，然后解决的问题。

=====
顺带做了mex混编，发现-fopenmp参数传进去无法被识别。

==> Caveats
On Apple Clang, you need to add several options to use OpenMP's front end
instead of the standard driver option. This usually looks like
-Xpreprocessor -fopenmp -lomp
You might need to make sure the lib and include directories are discoverable
if /usr/local is not searched:
-L/usr/local/opt/libomp/lib -I/usr/local/opt/libomp/include
For CMake, the following flags will cause the OpenMP::OpenMP_CXX target to
be set up correctly:
-DOpenMP_CXX_FLAGS="-Xpreprocessor -fopenmp -I/usr/local/opt/libomp/include" -DOpenMP_CXX_LIB_NAMES="omp" -DOpenMP_omp_LIBRARY=/usr/local/opt/libomp/lib/libomp.dylib
