MATLAB: Working legacy issues, I need a version to revision cross reference

revisionsversions

How can I find out what revision of matlab to use if I know the version?

Best Answer

Do you mean the relation:

Version        Release name    Release number
Matlab 7.2     R2006a          15
MATLAB 7.11.2  R2010bSP2       24

You need a table, e.g. https://en.wikipedia.org/wiki/Matlab#Release_history . The two different counting methods release and version do not follow a strict pattern. This feature is copied from Microsoft Windows, as the fancy ribbons in the GUI.

Writing an M-function, which finds the corresponding other key for a specific input, is not easy: There is e.g. a Version "7.9" and "7.9.1", the release number 24 belongs to R2010, R2010SP1 and R2010SP2.

[EDITED] If this is required dynamically, use FEX: MatlabRelVer

MATLAB: Running older versions of Matlab codes (Version 4.2c) on new versions of Matlab & Simulink

No, there's no program to automatically make the modifications to make MATLAB programs written for a twenty year old release run in a three year old release. However, rather than throwing the code away and starting anew, I advise you to try option 3: try to convert the code yourself.

In his The Origins of MATLAB article, Cleve posted a very short program that ran with the original Fortran version of MATLAB. He said that if he made one change, it ran with the current MATLAB at the time he wrote that article. It still runs today if you make that same one change. As long as you used documented functionality, a lot of the code should just plain work and hopefully much of the rest should require minor changes just like Cleve's example. If you get stuck on a piece of code that doesn't work and that you can't figure out how to modify/update from the context and the comments (the code is well commented, isn't it?) post a question about that small section of code here and/or ask Technical Support for help.

I'm not as sure about how easy it will be to convert the Simulink models because I don't use Simulink very frequently. According to the Release Notes there is a tool called Upgrade Advisor that was introduced in release R2012b. I've never used it so I don't know if it can convert version 1.0 models but I think it would be worth a try.

MATLAB: Installer for MATLAB R2010b Service Pack 2 creates incorrect Windows registry key

Along with this workaround, upgrading MATLAB to MATLAB R2011a will resolve this issue.

To discover the MATLAB Version

As a workaround for discovering the MATLAB version, execute VERSION at the command prompt, or look at the MATLAB Window Title Bar.

>> version
ans =
7.11.2.1031 (R2010b) Service Pack 2

To Prevent Installation of R2010bSP2 into the R2010bSP1 folder

To prevent MATLAB R2010b Service Pack 2 from installing into the R2010b Service Pack 1 directory take one of the following precautions:

Uninstall R2010b SP1 prior to installing R2010b SP2 or
Select a Custom installation and choose a new empty directory to install MATLAB into.

How to Fix the Registry Key

If you are using a third party product that relies on this registry key, the registry entry can be corrected after installing MATLAB R2010b Service Pack 2. (This workaround is not required for routine MATLAB usage.)

Modifications to registry entries can be made using the Windows Registry Editor. Before modifying your registry it is recommended that you back up the registry as a precaution.

To edit the registry key:

Click the Start Menu, then click "Run"
In the Run window, type "regedit", then click OK
Navigate to HKEY_LOCAL_MACHINE -> SOFTWARE -> MathWorks -> MATLAB -> 7.11.1
Confirm that the path specified for the installation is for R2010bSP2
Right click on 7.11.1 and select Rename
Change the text to 7.11.2

Once these steps have been completed, third party software that relies on the registry key will see the corrected version number in the registry key.
