I have Ubuntu 14.04.1 LTS.
When asked about creating 'symbolic links to MATLAB scripts' during installation, I mistakenly kept that unchecked. Now how can that be fixed without re-installing MATLAB all over again?
I used the following but I don't know if it is fixed:
ln -s $MATLAB/bin/matlab matlab
and how to create launcher and desktop shortcut? I did the following:
sudo apt-get install matlab-support
It seemed to be installing something but after it's done, I still don't have launcher and desktop shortcut. What do I do?

You need to create a symbolic link into a directory where is set in PATh. For exmaple, to create MATLAB symbolic link in /usr/local/bin, please try
sudo ln -s $MATLAB/bin/matlab /usr/local/bin/matlab
Then you can launch MATLAB by just typing matlab.
Also, to create a launcher in Desktop, after installing matlab-support please search MATLAB in Applications and drag & drop the icon to your Desktop.

Linking the "matlab" file didnt work for me. Says cannot find the license. I think I will need to redo the installation directly to /usr/local/bin

Oh wait, ignore. I see the problem. I did "su" not "sudo" and am still user "root". Once I exited the su then I became regular user again and the license is fine.

Ran in:
% Check for Simulink License
if ~license('test', 'Simulink')
error('Simulink license is not available. Please ensure you have a valid license.');
end
% Create a new Simulink model
model = 'InductionMachineModel';
new_system(model);
open_system(model);
% Add necessary blocks from Simscape Power Systems and basic Simulink libraries
% Ensure the block paths are correct for your Matlab version
add_block('powersys/Machines/Asynchronous Machine', [model '/Induction Machine']);
There is no block named 'powersys/Machines/Asynchronous Machine'

Caused by:
Error using solution (line 13)
Unable to load block diagram 'powersys'
add_block('simulink/Sources/Step', [model '/Input Voltage']);
add_block('simulink/Sinks/Scope', [model '/Scope']);
% Configure the Asynchronous Machine block with example parameters
% Adjust parameters according to the specific characteristics of your induction machine
set_param([model '/Induction Machine'], 'StatorResistance', '0.435');
set_param([model '/Induction Machine'], 'RotorResistance', '0.816');
set_param([model '/Induction Machine'], 'MutualInductance', '0.005');
set_param([model '/Induction Machine'], 'Inertia', '0.1');
set_param([model '/Induction Machine'], 'PolePairs', '2');
% Connect the blocks using the correct port numbers
add_line(model, 'Input Voltage/1', 'Induction Machine/1');
add_line(model, 'Induction Machine/1', 'Scope/1');
% Save and open the model to make sure it's ready to be run
save_system(model);
open_system(model);
% Set simulation parameters
set_param(model, 'StopTime', '10');
set_param(model, 'Solver', 'ode45', 'FixedStep', 'auto');
% Configure the Step block to simulate a change in input voltage
set_param([model '/Input Voltage'], 'Time', '1', 'Before', '0', 'After', '1');
% Run the simulation
simOut = sim(model);
% Extract and plot data from the scope
scopeData = get(simOut, 'ScopeData');
time = scopeData.time;
values = scopeData.signals.values;
% Plotting the results
figure;
plot(time, values);
title('Torque vs Time');
xlabel('Time (s)');
ylabel('Torque (Nm)');
