I am trying to compile cuda files into mex(matlab 2021b)

mexcuda mexGPUExample.cu

The error occurs:

warning: The selected C++ compiler is not supported for CUDA compilation. Searching for a supported compiler. 
> 位置：mexcuda (第 96 行) 
错误使用 mex
未检测到支持的编译器。有关选项，请访问 https://www.mathworks.com/support/compilers。
出错 mexcuda (第 168 行)
    [varargout{1:nargout}] = mex(mexArguments{:});

However , when I type:

mex -setup

I have tested the MinGW64 Compiler and it work properly

 MEX Configured to use 'MinGW64 Compiler (C)' for C compilation.
 
要选择不同的语言，请从以下选项中选择一种命令:
 mex -setup C++ 
 mex -setup FORTRAN

here are my gpu configurations:
