・Windows 10 SDK

and I got following error

Error using mex
No supported compiler was found. You can install the freely available MinGW-w64 C/C++ compiler; see Install MinGW-w64 Compiler. For more options, visit
https://www.mathworks.com/support/compilers.

>> mbuild -setup -v
'mbuild' requires MATLAB Compiler SDK.

I installed windows 10 SDK first and then installed Microsoft Visual C++ 2015-2019 x64 Redistributable

what am I missing?

Hi Daiki Kakiuchi,

It seems that the installed compiler for C++ is not supported for MATLAB compiler SDK. Kindly use the following documentation to identify the compatible C++ compiler for the MATLAB R2018b :

https://www.mathworks.com/content/dam/mathworks/mathworks-dot-com/support/sysreq/files/system-requirements-release-2018b-supported-compilers.pdf

Alternatively, MATLAB provides an add-on for MinGW-w64, 'MATLAB Support for MinGW-w64 C/C++/Fortran Compiler', which can be installed through the Add-On Explorer. To open the Add-On Explorer, navigate to the Home tab. In the Environment section, click the Add-Ons icon. You can refer the following documentation to know more about the add-on :
