Please install one of the supported compilers for this release as listed at:http://www.mathworks.com/support/compilers/R2017b.htmlMATLAB must be restarted after the compiler is installed.

>> mex -setup
MEX 配置为使用 'MinGW64 Compiler (C)' 以进行 C 语言编译。
警告: MATLAB C 和 Fortran API 已更改，现可支持
包含 2^32-1 个以上元素的 MATLAB 变量。您需要
更新代码以利用新的 API。

mex -setup FORTRAN
我已经配置好了mingw64了

问题是我配置好如三楼所示的编译器，MATLAB 2017b，MinGW64。生成dll文件时还会出现二楼的错误
