I am using matlab online What should I do

The header file ('tmwtypes.h') is missing from the generated files because all the files which are a part of MATLAB installation (present in the ‘MATLABROOT\extern\include’ directory) does not get copied in the folder of the generated code.

It is expected that since these files are already available in the MATLAB directory, to compile these files we just need to include the path of these files in the ‘include’ directory of the external compiler.

In contrast, other MATLAB files (like rtwtypes.h) are generated because these files are not available in the MATLAB installation directory. These files are customized to the specific project for which code is generated and are not generic files.

As a workaround, to get all the files in the generated directory, package option can be used which will create a ZIP folder with all the files included. This option can be used if the generated code need to be relocated to another development environment. For details on this please refer to the below link:

Package Code for Other Development Environments (mathworks.com)

In addition, the necessary files to include in the external compiler may be found in the MK file, if the Coder is set to generate one.
