How can I determine the update release number of my current MATLAB session?

OPTION 1: Using the "matlabRelease" command

Since the release of MATLAB R2020b, the "matlabRelease" command provides a straightforward way to determine both the release and the update number. When you execute the following command:

>> releaseInfo = matlabRelease

You receive output similar to this:

releaseInfo = 

  matlabRelease with properties:

    Release: "R2022b"
      Stage: "release"
     Update: 0
       Date: 24-Aug-2022

This output indicates that the "Update" is 0, signifying that you are using the General Release of MATLAB R2022b.

For more information about the "matlabRelease" command, refer to the following link.

OPTION 2: Using the "version" command

The "version" command provides a string containing the the complete version and release number for the currently running MATLAB instance. For example, when you run:

>> version

ans =

    '24.1.0.2689473 (R2024a) Update 6'

This output indicates that the "Update" release number is 6.

There is also a "-description" flag for "version" that returns just the update string:

>> version -description

ans =

    'Update 6'

NOTE: When you are using a General Release, there will be no Update indicated by "version":

>> version

ans =

    '9.13.0.2049777 (R2022b)'

As a consequence, it is also expected that an empty string is returned when using "version -description" in a General Release:

>> version -description

ans =

  0×0 empty char array

For further details on the "version" command, consult the documentation:

OPTION 3: Using "About MATLAB"

In addition to the command-line methods, you can also find the update number interactively through the MATLAB Desktop GUI. Access this information by navigating to Help > About MATLAB.
