Question

Is there a way to get the version of MATLAB without launching the engine? When launched (in non-GUI mode) it prints the version to stout – but I am using it remotely from Java and so that output is not available.

As an alternative, is there a way to get the version from within MATLAB?

By ‘version’ I mean preferably the double-string number, e.g “7.13” as opposed to the release number e.g “R2011b”.

Thanks!

As Jonas said, the version command is your friend. Use

v = version

to get the numeric version (followed by the “R-release” version) in a string, as follows:

v =
7.12.0.39132 (R2011a)

Then, you should be able to parse the string to get just the beginning numeric part.

See the MathWorks documentation for VERSION at

http://www.mathworks.com/help/techdoc/ref/version.html

for more information.

An additional hint; if you’re looking for the version number to ensure that the installed MATLAB is no older than (some particular release number), check out the documentation for VERLESSTHAN, at http://www.mathworks.com/help/techdoc/ref/verlessthan.html It might help you solve your problem without having to parse the string yourself.
