Note: Georgetown’s MATLAB license is available for Georgetown students, faculty, and staff. Students can either download MATLAB from the software webstore or access MATLAB.
- MATLAB License Number: 4. Operating System: Microsoft Windows 10 Home Version 10.0 (Build 17134) Java Version: Java 1.8.0144-b01 with Oracle Corporation Java HotSpot(TM) 64.
- Large number of available functions. Great for data visualization. Available across platforms. Easy to use debugging tools. Cons: Resource intensive - slow to load. License price is high. Overall: MATLAB is a great tool which can be used for data analysis, computation or visualization. It can also be used for simulations and modeling systems.

Syntax
Description
licensereturns the license number for this MATLAB. The return value is always a string but is not guaranteed to be a number. The following table lists text strings that license can return.| String | Description |
'demo' | MATLAB is a demonstration version |
'student' | MATLAB is the student version |
'unknown' | License number cannot be determined |
Matlab License Types
license('inuse')returns a list of licenses checked out in the current MATLAB session. In the list, products are listed alphabetically by their license feature names, i.e., the text string used to identify products in the INCREMENT lines in a License File (license.dat). Note that the feature names returned in the list contain only lower-case characters.
S = license('inuse') returns an array of structures, where each structure represents a checked-out license. The structures contains two fields: feature and user. The feature field contains the license feature name. The user field contains the username of the person who has the license checked out.
license('test',feature)tests if a license exists for the product specified by the text string feature. The license command returns 1 if the license exists and 0 if the license does not exist.
The feature string must be a license feature name, spelled exactly as it appears in the INCREMENT lines in a License File. For example, 'Identification_Toolbox' is the feature name for the System Identification Toolbox. The feature string is not case insensitive and must not exceed 27 characters in length.
| Note Testing for a license only confirms that the license exists. It does not confirm that the license can be checked out. For example, license will return 1 if a license exists, even if the license has expired or if a system administrator has excluded you from using the product in an options file. |
license('test',feature,toggle)enables or disables testing of the product specified by the text string feature, depending on the value of toggle
. The parameter toggle can have either of two values:'enable' | The syntax license('test',feature) returns 1 if the product license exists and 0 if the product license does not exist. |
'disable' | The syntax license('test',feature) always returns 0 (product license does not exist) for the specified product. |
Note Disabling a test for a particular product can impact other tests for the existence of the license, not just tests performed using the license command. |
result = license('checkout',feature)checks out a license for the product identified by the text string feature. The license command returns 1 if it could check out a license for the product and 0 if it could not check out a license for the product.
