How can I determine what add-ons I have installed?

I would like to know what products and other toolboxes are installed into my installation of MATLAB, and also what functions are provided with the toolboxes.

Using the Add-On Manager 

The following answer applies to MATLAB version R2015b or later only. 

View and manage all installed add-ons using the Add-On Manager.  

To open the Add-On Manager: 

1. In MATLAB, go to the Home tab. 

2. Select Add-Ons > Manage Add-Ons. 

MATLAB displays a list of MathWorks products, toolboxes, and add-ons installed on your machine. 

To view the function list for an add-on: 

1. Select the add-on in the Add-On Manager. 

2. In the options menu on the right of the add-on, select View in Add-On Explorer. The Functions tab shows the list of functions included with the add-on. 

Using the Command Line  

The following answer applies to MATLAB version R2017b or later only.

To produce a list of installed Community add-ons, use the 'matlab.addons.installedAddons' command:

The following answer applies to all versions of MATLAB. 

To produce a list of installed MathWorks products and add-ons, use the 'ver' command:

To produce a list of the functions available in MATLAB, use the 'help' function:

TBH it's really sad that there is no easy programmatic way of checking whether a toolbox is ready to be used, i.e., installed and has a license.

To check if you have installed a specific toolbox, you can use the existing function in FileExchange called isToolboxAvailable . The usage is as follows:

result = isToolboxAvailable('image processing toolbox','error');

[Thomas McKay-Smith]

Since R2006a you can use

result = license('test','image processing toolbox')

making isToolboxAvailable somewhat redundant.

To reproduce my comments on the FEX page: This works to check if a product is _installed_. It does not check whether a _license_ is available. Either of these may occur without the other being true, so to check whether a toolbox can actually be used, one should check both. Initially, I thought that this could be achieved by adding a simple one-liner after "result = all(ismember(toolboxName,installedToolboxes));":

result = result && license('test', regexprep(toolboxName, ' ', '_'));

Unfortunately, this doesn't work for all toolboxes, because there are some toolboxes for which the relation between the 'Name' and the 'feature name' is more complex. E.g., the 'Statistics and Machine Learning toolbox' has the feature name 'Statistics_Toolbox' (probably for historical reasons). I am not sure if there is a general way to translate one into the other.

This FEX submission appears to solve this problem; see my other answer: https://de.mathworks.com/matlabcentral/fileexchange/77275-matlabtoolboxcheck

This file exchange submission appears to be a quite comprehensive solution to this problem:

https://de.mathworks.com/matlabcentral/fileexchange/77275-matlabtoolboxcheck

It checks both whether a toolbox is installed and whether a license is available. Works for lists of toolboxes as well.

In the unit test framwork TTEST is an experimentally function available EXPECT_TOOLBOX, which checks the availability of toolboxes. Its usage is quite straightforward, for some toolboxes are even hardcoded shortcuts possible, e.g.:

EXPECT_TOOLBOX('parallel')

checks whether the parallel toolbox is installed and licenced.

For toolboxes with no shortcuts yet, one has to give the exact toolbox name, e.g.:

EXPECT_TOOLBOX('Distrib_Computing_Toolbox')

But, the function is still experimental.
