How to Install a Toolbox in MATLAB

Method 1: Install via MATLAB Add-On Explorer (GUI)

1. Launch MATLAB and navigate to the Home tab at the top toolbar.
2. Click the Add-Ons drop-down menu and select Get Add-Ons.
3. Use the search bar in Add-On Explorer to locate toolboxes like Control System Toolbox, Image Processing Toolbox, Signal Processing Toolbox, or Simscape.
4. Click Add to MATLAB or Install and complete authentication.

Method 2: Programmatically Verify Installed Toolboxes & Licenses

Check if required toolboxes and licenses are active before running your MATLAB scripts:

% Check all installed toolboxes
installedToolboxes = ver;
disp({installedToolboxes.Name}');

% Programmatically test specific toolbox licenses
hasSignalProc = license('test', 'signal_toolbox');
hasImageProc  = license('test', 'image_toolbox');
hasControl    = license('test', 'control_toolbox');

fprintf('Signal Processing Available: %d\n', hasSignalProc);
fprintf('Image Processing Available:  %d\n', hasImageProc);
fprintf('Control System Available:    %d\n', hasControl);

Method 3: Install Custom `.mltbx` Package Files

If you downloaded a custom toolbox file (extension .mltbx) from File Exchange or GitHub, install it in one line:

% Command window installation for .mltbx file
matlab.addons.install('MyCustomToolbox.mltbx');

% Verify installed add-ons list
addons = matlab.addons.installedAddons;
disp(addons);

Method 4: Manual Path Configuration (`addpath` / `savepath`)

For custom script folders packaged without an installer, permanently add them to MATLAB's search path:

% Add folder and all subfolders to active search path
addpath(genpath('C:\MyMatlabToolboxes\CustomPackage'));

% Permanently save search path across MATLAB restarts
savepath;
