I am trying to activate and use MATLAB. Every time I start MATLAB, it asks me to activate, even though I complete the process and it states activation is complete. Portable version of Matlab.

As such, it can easily be accessed programmatically. ImageAnalyst, a well-respected member of the Matlab community and a frequent CSSM (newsgroup) and FEX (File Exchange) contributor, whether it is possible to retrieve the name of the Editor’s currently edited file. The answer is that this is very easy, but I decided to use this opportunity to show how other interesting things can be done with the Editor. Before we start, it should be made clear that this entire article relies on MathWorks internal implementation of the Editor and Desktop, which may change without prior notice in future Matlab releases. The code below appears to work under Matlab 6 & 7, but users who rely on forward compatibility should be aware of this warning. We start by retrieving the Editor handle. This can be done in a number of ways. The easiest is via the Matlab desktop. Try% Matlab 7 desktop = com. GetInstance; jEditor = desktop. GetGroupContainer ( 'Editor' ). GetTopLevelAncestor;% we get a com.mathworks.mde.desk.MLMultipleClientFrame object catch% Matlab 6% Unfortunately, we can't get the Editor handle from the Desktop handle in Matlab 6:%desktop = com.mathworks.ide.desktop.MLDesktop.getMLDesktop;% So here's the workaround for Matlab 6: openDocs = com. GetOpenDocuments;% a java.util.Vector firstDoc = openDocs. ElementAt ( 0 );% a com.mathworks.ide.editor.EditorViewContainer object jEditor = firstDoc. GetParent;% we get a com.mathworks.mwt.MWTabPanel or com.mathworks.ide.desktop.DTContainer object end Now that we have the Editor handle, let’s retrieve its currently open (active) file name from the Editor’s title. Suara sirene mp3. % Actions via built-in methods: jEditor. SetResizable ( 0 ); jEditor. SetStatusText ( 'testing 123.' SetTitle ( 'This is the Matlab Editor' );% Equivalent actions via properties: set (jEditor, 'Resizable', 'off' ); set (jEditor, 'StatusText', 'testing 123.' ); set (jEditor, 'Title', 'This is the Matlab Editor' ); Actually, the jEditor handle has over 300 invokable methods and close to 200 properties that we can get/set. Perhaps the easiest way to find interesting things we can programmatically do with the Editor handle, is to use my utility on the File Exchange.

Ruben – that was a hard question that kept me digging for hours. I discovered (via the FindJObj utility) that the bookmarks are displayed in a panel called ‘ExecutionArrowDisplay’ of class com.mathworks.mde.editor.ExecutionArrowDisplay$ExecutionPanel. I do not know whether the list of bookmarks are contained within this object, although I suspect they are. In any case, I did not find a method to programmatically retrieve this list since the ExecutionPanel object does not expose any method to do so. So, the only way I could find is to loop over all the editor’s open files, and invoke the editor’s default action for (which is the ‘next-bookmark’ action reported by the EditorMacro utility) in a loop until you detect coming back to an earlier line number. It’s ugly, but it should work. The reverse, setting bookmarks, could be done in a similar fashion, using the ‘toggle-bookmark’ action. I think it could be a great File Exchange utility. Care to try it? If you get stuck I can help out. Hi, I sent this question on MATLAB central but received no answer, so I post it here again in case you’ve not seen it! I have a time tracking software that records the time I spend on each application. It recognizes the applications by their window caption. I’m used to have the MATLAB editor docked into the main window, so all my working time in MATLAB is reported under the name of “MATLAB 7.8.0 (2009a)”. I’m thinking of a way to change the main window title to the name of the document I’m currently working on. Thanks to undocumentedmatlab.com now I know how to get the name of the active document and how to change the window title by accessing related java components.
