Additional license data - Undocumented Matlab

Matlab’s license function returns the primary license number/ID used by Matlab, but no information about the various toolboxes that may be installed. The ver function returns a bit more information, listing the version number and installation date of installed toolboxes (even user toolboxes, such as my IB-Matlab toolbox). However, no additional useful information is provided beyond that:

>> license
ans =
123456   % actual number redacted

It is sometimes useful to know which license number “owns” which product/toolbox, and the expiration date is associated with each of them. Unfortunately, there is no documented way to retrieve this information in Matlab – the only documented way is to go to your account section on the MathWorks website and check there.
Luckily, there is a simpler way that can be used to retrieve additional information, from right inside Matlab, using matlab.internal.licensing.getFeatureInfo:

>> all_data = matlab.internal.licensing.getFeatureInfo
all_data =
  23×1 struct array with fields:
    feature
    expdate
    keys
    license_number
    entitlement_id
>> all_data(20)
ans =
  struct with fields:
           feature: 'optimization_toolbox'
           expdate: '31-mar-2018'
              keys: 0
    license_number: '123456'
    entitlement_id: '1409891'
>> all_data(21)
ans =
  struct with fields:
           feature: 'optimization_toolbox'
           expdate: '07-mar-2017'
              keys: 0
    license_number: 'DEMO'
    entitlement_id: '3749959'

As can be seen in this example, I have the Optimization toolbox licensed under my main Matlab license (123456 [actual number redacted]) until 31-mar-2018, and also licensed under a trial (DEMO) license that expires in 3 weeks. As long as a toolbox has any future expiration date, it will continue to function, so in this case I’m covered until March 2018.
We can also request information about a specific toolbox (“feature”):

>> data = matlab.internal.licensing.getFeatureInfo('matlab')
data =
  3×1 struct array with fields:
    feature
    expdate
    keys
    license_number
    entitlement_id
>> data(1)
data =
  struct with fields:
           feature: 'matlab'
           expdate: '31-mar-2018'
              keys: 0
    license_number: '123456'
    entitlement_id: '1409891'

The drawback of this functionality is that it only provides information about MathWorks’ toolbox, not any user-provided toolboxes (such as my IB-Matlab connector, or MathWorks’ own GUI Layout toolbox). Also, some of the toolbox names may be difficult to understand (“gads_toolbox” apparently stands for the Global Optimization Toolbox, for example):

>> {all_data.feature}
ans =
  1×23 cell array
  Columns 1 through 4
    'curve_fitting_toolbox'    'database_toolbox'    'datafeed_toolbox'    'distrib_computing_toolbox'
  Columns 5 through 8
    'distrib_computing_toolbox'    'excel_link'    'fin_instruments_toolbox'    'financial_toolbox'
  Columns 9 through 15
    'gads_toolbox'    'gads_toolbox'    'image_toolbox'    'image_toolbox'    'matlab'    'matlab'    'matlab'
  Columns 16 through 20
    'matlab_coder'    'matlab_coder'    'matlab_report_gen'    'matlab_report_gen'    'optimization_toolbox'
  Columns 21 through 23
    'optimization_toolbox'    'optimization_toolbox'    'statistics_toolbox'

A related undocumented builtin function is matlab.internal.licensing.getLicInfo:

% Information on a single toolbox/product:
>> matlab.internal.licensing.getLicInfo('matlab')
ans =
  struct with fields:
     license_number: {'123456'  'Prerelease'  'T3749959'}
    expiration_date: {'31-mar-2018'  '30-sep-2016'  '07-mar-2017'}
% Information on multiple toolboxes/products:
>> matlab.internal.licensing.getLicInfo({'matlab', 'image_toolbox'})  % cell array of toolbox/feature names
ans =
  1×2 struct array with fields:
    license_number
    expiration_date
% The full case-insensitive names of the toolboxes can also be used:
>> matlab.internal.licensing.getLicInfo({'Matlab', 'Image Processing toolbox'})
ans =
  1×2 struct array with fields:
    license_number
    expiration_date
% And here's how to get the full list (MathWorks products only):
>> v=ver; data=matlab.internal.licensing.getLicInfo({v.Name})
data =
  1×16 struct array with fields:
    license_number
    expiration_date

I have [still] not found any way to associate a user toolbox/product (such as my IB-Matlab) in a way that will report it in a unified manner with the MathWorks products. If anyone finds a way to do this, please do let me know.
p.s. – don’t even think of asking questions or posting comments on this website related to illegal uses or hacks of the Matlab license…

Try “ver -support” to get a listing with license numbers for each toolbox.

@Mikhail – yes, but (alas) without expiration dates…

This may get you what you want

function out = getInstalled()
    % Problem with the support_packages implementor
    knowGoodTypes = {'toolbox','app','product','zip'};
    out = {};
    k = 1;
 
    % Get implementors
    jImplementors = com.mathworks.addons_common.AddonManagerFactory.getImplementors();
    pause(0.5);
 
    iter = jImplementors.listIterator;
    while iter.hasNext
        jImp = iter.next;
        type = char(jImp.getAddonTypeServiced);
        if ismember(type, knowGoodTypes)
            try
                jInstalledList = jImp.getInstalled;
                lenInstalled = length(jInstalledList);
                for itr = 1 : lenInstalled
                    jInstalled = jInstalledList(itr);
                    itype = char(jInstalled.getInstalledAddOnsMetadataToBeSentToManager.getDisplayType);
                    iname = char(jInstalled.getName);
                    iver =  char(jInstalled.getVersion);
                    idate = char(jInstalled.getInstalledDate.toString);
                    out{k,1} = [itype,' : ',iname,' ', iver,' ', idate];
                    k = k+1;
                end
            catch
            end
        end
    end
 
end

Hi Yair,

I noticed “Statistical Graphics Toolbox” in your version listing. What is that, if I may ask, please? I couldn’t find any info on my own. Thanks in advance.

Yair Altman February 17, 2017 at 09:41 Reply

@Brad – This is the graphics package which is part of the Lightspeed toolbox by Tom Minka.

Is there any way to return a floating toolbox license without closing the Matlab session? Its not uncommon for me to find that somewhere in my code base I accessed an obscure toolbox which another user now wants to use. At present the only way to that I know of to release the license is to stop what I am doing and shut down Matlab.
