Hi Roshan,

I understand that you are facing an error while trying to open Simulink in MATLAB R2018a. This issue is likely due to missing shared library dependencies that MATLAB requires to function properly.

To diagnose the problem, you can start by using the "ldd" command in your terminal to identify which shared libraries are missing. For example, run:

ldd /usr/local/MATLAB/R2018a/bin/glnxa64/libmwsl_lib_browse2.so

This command will list all dependencies and clearly indicate any that are not found on your system. If any are missing, you may need to install the corresponding packages via "apt".

If resolving the dependencies manually does not fix the issue or too many libraries are missing, you can try reinstalling MATLAB, preferably a newer version, for better compatibility and updated libraries.

Refer to the following MATLAB Central link for other possible solutions to similar issues:

Hope it helps.
