Test for compatibility in Matlab

I'm working with an open source Matlab toolbox which, according to its creators, is compatible for versions of Matlab over 7.6, i.e., R2008a. I tried to run it in R2011b and it threw the exception: Undefined variable "Simulink" or class "Simulink.Mask.create"

Since: 1- Simulink is installed and functional in this R2011b; 2- I have already run the same code in a R2014b successfully; I conclude that this is a problem of compatibility -In contrast to their claim, their code is compatible for some version later than R2011b-.

I wish I could contribute with them by directly telling them, not only that their code is not compatible with Matlab 7.6, but also the earliest version in which the statement associated with Simulink.Mask.create would run.

So, in precise terms, MY QUESTION IS: Given a command, built-in function, namespace resolution sequence, or whatever feature that I can find in some version of Matlab, what is the way of knowing what is the earliest version in which that feature is active?

I have tried http://www.mathworks.com/help/simulink/release-notes.html which is not searchable or navigable the way I wish it was.

Solution

  • This is a common problem. This page talks of the same problem - claiming that there is no good solution... It does however come with a smart way of searching through the release notes:

    1. Click on the bottommost unexpanded release, to expand the it.
    2. Click on "expand all" all link to expand all link just below.
    3. If any unexpanded releases remain goto 1.
    4. Now use the browser search functionality (often ctrl+f) to search the fully expanded page.

    Good luck!

    EDIT: To see older releases too you need to start with the following step:

    0: Click the link in the bottom saying "View release notes for older releases".

    And then continue like above.
