It is found that the bold part is that the compiler is not found VS2019 Why . because matlab Finding the compiler is usually through the registry to find the corresponding compiler and SDK.
Open the registry ： Press down win+r key , Input regedit Open registry editor .
seek matlab The corresponding file method is as follows ：
Mainly looking for two files ：HKEY_CURRENT_USER and HKEY_LOCAL_MACHINE, They correspond to each other Matlab Medium HKCU and HKLM

according to MATLAB Error messages in , Corresponding search ：
1. Find the way ：’HKLM\SOFTWARE\Microsoft\VisualStudio\SxS\VS7’ 16.0‘
Add string ：
Right click to add a string , Name it 16.0, Change the value to VS2019 Installation directory .
————————————————
And then again in matlab Run in mex command ：
Found compiler VS2019, Just choose the language you want to use .
