bash: matlab: command not found

Note: While invoking the MATLAB application from the Bash command line, the path to the MATLAB executable may be undefined in your Bash terminal. Consequently, calling MATLAB on the command line via,

matlab

would lead to such error messages as the following,

bash: matlab: command not found

To resolve the error, you need to provide the full path to the MATLAB executable. On macOS, the full path to the MATLAB executable typically is,

/Applications/MATLAB_R2020a.app/bin/matlab

and on Linux,

/usr/local/MATLAB/R2020a/bin/matlab

where in both cases you will have to replace R2020a with the MATLAB version installed on your system. You can also execute the following command on your Bash terminal to add a MATLAB executable alias to your ~/.bashrc file so that every time a bash terminal is opened on your system, or when you execute source ~/.bashrc in your current Bash session, it would automatically recognize the path to the MATLAB executable,

echo "alias matlab=path_to_matlab_executable" >> ~/.bashrc

where in the above command, you will have to replace path_to_matlab_executable with the correct full path to the MATLAB executable on your system.

If for any reasons, you can not find the MATLAB executable's path, you can open a MATLAB session via the Linux / macOS search software. Once MATLAB session is open, type in the MATLAB command line,

matlabroot

to get the root installation path of MATLAB. You can find information about this command on MATLAB website. Then, add /bin/matlab to this path to construct the full path to the MATLAB executable and repeat the above instructions again.
