Introducing MATLAB R2012a 9

Posted by Michael Katz,

It’s March! That means Spring is in the air and a new version of MATLAB is available! Let’s look an overview of the new desktop features:

Improved Variable Editor Sorting
Variable Editor Sorting/Transpose You can now transpose and sort variables using the context menu options in the Variable Editor. Variable contents are sortable based on single or multiple column selections.

MATLAB Dock Menu on Mac
MATLAB R2012a Mac Doc menu The MATLAB Dock menu now lists open windows and documents associated with the running MATLAB. Choosing an open document will bring it to the front. In addition, the MATLAB Dock menu includes the new option “Open Additional Instance of MATLAB”, which starts another instance of MATLAB–if you need more MATLABs for some reason.

Improved Rendering in MATLAB Web Browser
Modern web rendering on windows R2012a The MATLAB Web browser uses a new HTML rendering engine on Windows. This new engine provides better rendering, particularly on 64-bit systems.

PUBLISH supports syntax highlighted sample code
Syntax Highlighted Sample Code When using cell markup for publishing, you can have syntax-highlighted code fragments in the text part. To do this, use Cell > Insert Text Markup > Syntax Highlighted Sample Code, or insert three spaces between the “%” and the first character of code.

XLSREAD reads XLSX on all platforms
The xlsread function now reads data from XLSX files on all platforms, including support for specifying the range and worksheet number.

Matlab’s gui-building capabilities were horribly outdated many many years–even decades–ago, and I’ve been hearing (also for years and years) that a revamped system is on its way.


I guess I have really given up on this pipe dream, but I still drop by to be slightly (though less and less) disappointed for every new release. Apparently it is not a priority for Mathworks.

Any talk of adding tabs to the browser?

Jolle, I’ve been wondering about the gui tools also. The lack of guide development is disappointing.

@Jolie and @John,

I understand the frustration with GUIDE. I still have nothing to add on this matter, other than its an area we are working on, but no date on when we’ll have an update.

Not yet on the tabbed browser.

Not yet. You can watch the bug report that’s attached to the solution you linked. This will be updated when the issue is fixed.

Glad to hear about XLSREAD now reading XLSX on all platforms. That was unfortunate for earlier versions on Mac.

Could we get a search bar for the Help and Editor windows? For example, in the longer help documents (e.g, axes properties), it would be nice to able to search the document without using Command-F. Firefox-style type-to-search could also be employed for the Help.

The Editor’s variable-name-changer using Shift-Enter introduced a few versions ago is great.

How about moving all toolboxes to Application Support folder? It would be nice to have them in a logical place. Plus it is much easier to add new toolboxes using the Set path… dialog.
