the thing is strfind or strrep wont detect the inconsistency i am talking about. It shows error something like this:

>> ans{1,1}

ans =

F@@@@@@@@@@@@@@@7

>> strrep (ans, ‘@@@@@@@@@@@@@@@@’,”);
strrep (ans, ‘@@@@@@@@@@@@@@@’,”);
↑
Error: String is not terminated properly.

>>

use the strrep function

I am using pretty old version of Matlab 7.6.0 (R2008a) and I noticed that there is a file named mfiletemplate.m in toolbox/matlab/codetools/.

I suspect that it should be used for templating a new file, i.e., I click on the New M-File and it shows a new m-file with some template (containing copyrights, etc.). However, it seems it is never called and I can’t find any documentation about this function. Do you know this function and how is it used?

In general, my problem is, that I would like to create an m-file containing some header each time I click on New M-file icon. I can do that using custom shortcuts (there is plenty of codes on fileexchange), but the main problem is that the custom shortcuts are not visible in editor window (only desktop). Is there probably a way to “hack” the new m-file icon that it would call my own script?
Thank you a lot.

@Royi – setBounds is not a field but a method (that accepts either a java.awt.Rectangle object or 4 int values as input parameter(s)). As far as I can tell, it still exists in R2016a, you simply have a usage bug in your code.

It seems something changed lately (At least on MATLAB R2016a).
For most methods (Such as changing the bounds / size properties) I get the following error (This case for setBounds):

No public field setBounds exists for class com.mathworks.mde.desk.MLMultipleClientFrame.

How can one now access those properties?

One could still edit some of the properties by:

inspect(jEditor).

Thank You.

I’m writing a function in Matlab that will auto-generate header information for a Matlab .m file using key-phrases and context throughout the file. It would be great if I could also auto-wrap comments programmatically, do you know of a way to do this either through Matlab’s matlab.desktop.editor class or the Java classes discussed on this page? Ideally, it would be equivalent to manually selecting text in the editor, then pressing CTRL+J to wrap any selected comments.

Thank you for this website, it’s been helpful on many occasions!

@Alberto – try SyntaxTextPane.

If you liked my book, please be kind enough to post a favorable review of it in Amazon (link)

Many thanks for your (un)documented work and book.

Here is my question:

[SHORT]
Is there an easy way to emulate the in ‘block’ C code editing
that is available in the “Embedded Matlab Function” (SimulinkBlock).

[MORE Detailed]
I was using the old JSyntaxPane Java library, to call for inline editing of hidden block userdata field, and to replace the ugly Usercode blocks managed by the “ccextopenfcn”.

However, JSyntexPane Lib is now a bit obsoleted and not more maintained. Therefore I was intended to replace it with more efficient and portable EmbeddedMatlabEditor, thus minimizing also external java dependencies.

Using the post guidance it is easy to open the Docs and flush some actions, but I did not found clear methods to switch syntax parsing to “C” and to intercept the file saving actions (even if a save interceptor method exist in the com.mathworks.mde.editor.MatlabEditorApplication)

Thank you again for your work.

[EVEN MORE]
Here is an example how I integrated the JSyntax

function [r,ok] = coloreditjava(s, Title)
import javax.swing.*

% First we create a new Figure with some properties for better look
fa = figure('NumberTitle','off','Name',['SF: ' Title],'DockControls','on',...
'Toolbar','none','Menubar','none');
sz=get(fa,'OuterPosition');
set(fa,'OuterPosition',[sz(1)-340 sz(2)-300 680 730]);
 
% JSYNTAX pane is an external JAR library which handles a color
% editing textbox. The box is similar in functionalities to 
% scintilla, but the use of java here makes the tool portable
% among different platforms (OSX/WIN7 tested)
jsyntaxpane.DefaultSyntaxKit.initKit();
codeEditor = JEditorPane();
% We used the default language as JAVA since is similar to 
% C and the 'C' color editing is not mature enough in the
% external toolbox
codeEditor.setContentType('text/java');
%codeEditor.read(java.io.StringReader(s), 'text/java');

% Secondly we attach and resize this widget to our figure
% we reserve 25 points edge alonside
srcPane = JScrollPane(codeEditor);
[jEdit,EditContainer] = javacomponent(srcPane, [20,40,640,700], fa);
set(fa, 'ResizeFcn',{@myResize, EditContainer});
codeEditor.setEditorKit(jsyntaxpane.syntaxkits.JavaSyntaxKit());
codeEditor.setText(char(s));        

% on the bottom we attached two Java buttons which are defined on the
% fly. Any java swing component may be used here. This is not
% officially supported matlab, but working well since several 
% releases
jButton = javacomponent(javax.swing.JButton('Ok'), [20,6,100,24], gcf);
jjButton2 = javax.swing.JButton('Cancel');
jButton2 = javacomponent(jjButton2,                 [150,6,100,24], gcf);

% Callback events on the Java components can be handled through
% standard matlab function. The push action here are attached to 
% two functions.
hButton = handle(jButton, 'CallbackProperties');
set(jButton, 'ActionPerformedCallback', @CancelCallback);
hButton2 = handle(jButton2, 'CallbackProperties');
set(jButton2, 'ActionPerformedCallback', @OkCallback);

% Uwait waits for the the window to exit and determines is the user
% committed some editor changes or not. In the first case the Java
% string is copied to a matlab string.
uiwait(fa);

if length(jjButton2.getText()) == 0
    r = s; % Take Original
    ok = 0;
else    
    r = char(codeEditor.getText());
    ok = 1;
end

%close fa;

% Matlab callback function
function CancelCallback(hObject, hEventData)
    close(gcf); %exits uwait
end


function OkCallback(hObject, hEventData)
    set(hObject,'Text','');
    close(gcf); % exits uwait
end

% If window is resizable this function resizes also the relevant
% editing box inside. This is not automatically operated by matlab
% when using java swing components.
function myResize(hObject, hEventData, EditContainer)
    sz=get(hObject,'Position');
    set(EditContainer, 'Position',[20 40 (sz(3)-40) (sz(4)-50)]);
end

end
