Problem Description:

A .c file needs to be executed and compiled by Matlab R2016a to execute the subsequent .m file command line window:

>> mex -setup
错误使用 mex

Matlab R2016a needs to be installed correctly
mingw-w64-install.exe
tdm64-gcc-4.9.2.exe

1. Failure experience

Reference: Matlab R2016a gcc 4.9.2 installation

Find the relevant software installation method to install and findinstallation failed:
(The root cause may be due to the problem of version update) The
specific problems are as follows:
1. To install the mingw-w64 software, you need to select the version: 4.9.2; (select the default location to install) the

result is an installation error
2. Install tdm64-gcc-4.9.2 , Click Creat , prompt, need to download the latest version .

2. Success method

Prompt to download the latest version, then let's install the latest version!

Reference: How to configure MinGW-w64 C/C++ compiler in Matlab 2016a

(1) Download MinGW-w64 C/C++ compiler

Download the tdm64-gcc-9.2.0.exe installation package

(2) Install MinGW-w64 C/C++ compiler

Note: Install according to the default path
If it is installed on other disks, when adding the path, " D:\TDM-GCC-64" is not an internal or external command, nor is it an executable program"

(3) Set as system environment variable

Right-click the computer and select Properties-Advanced System Settings-Advanced-Environment Variables, select "New" under System Variables :
Variable name:MW_MINGW64_LOC
variable:C:\TDM-GCC-64
Type the variable value in the location where the MinGW-w64 compiler is installed. The default installation is "C:\TDM-GCC-64" (Note: "C:\TDM-GCC-64" is the installation directory of MinGW)

(4) Use MATLAB to set MW_MINGW64 as a temporary environment variable

Run the following command in the MATLAB command window:

>> setenv('MW_MINGW64_LOC','C:\TDM-GCC-64')

"C:\TDM-GCC-64" is the installation directory of MinGW. In this method, you need to run this command every time you start MATLAB for MATLAB to use MinGW correctly. Order to your "startup.m"File. This command is executed every time MATLAB starts.
