explorestruct

MATLAB Utility for exploring structures and plotting its fields.

Description

CRC-ExploreStruct v.1.1
MATLAB Utility for exploring structures and plotting their fields.

This GUI is an updated and enhanced version of the StructBrowser utility submitted to MATLAB Central in May 2003. It comes with new interface and an enhanced display. It uses Microsoft TreeView control to display and explore any kind of MATLAB structures. The CRC ExploreStruct was designed to expose the contents of the array struct to any depth and plot any of the components. This tool is very useful for programmers using structures in their code.

• MATLAB release: MATLAB 7.0.1 (R14SP1)
• Other requirements: Does not work with MATLAB 6.1 and 6.5

[Gerd Kunert]

The tool seems to be quite useful.
Two comments:
a) replace line 247 by
   fields{length(fields)+1, 1} = cNode.getValue;
such that exlorestruct also works with Matlab 7.0.1.

b) For variables that can be displayed in a single line (such as a string), it would be useful to display the variable content as well (not only in the Matlab window)

This is a nice tool that provides a convenient way to visualize structures. I was keen on using it with ExcelFileSummary; it works, but it seems to have a limited viewing depth for nested structures. Still, very nice.

doesn't work in Matlab Rel. 13!
What can I do to make it work on rel. 13?

[Francis Pieraut]

Doesn't work

[Daniel Eottevenyi]

Very good tool, but there is a bug in line 264 (sometimes false data will be shown unless it is replaced):
 if(field(d+2)==')')
     idx = str2num(field(d+1));
 else
     if(field(d+3)==')')
        idx = str2num(field(d+1:d+2));
     else
        idx = str2num(field(d+1:d+3));
     end
 end

I liked StructBrowser, but this one doesn't work for me. I get a message:

??? Error using ==> explorestruct>myExpfcn4
The uitree node type is not recognized. You may need to define an ExpandFcn for the nodes.

Any one with suggestions???

[Ami Drory]

I like it, but it would be good to extend this tool to be able to explore classes, cells etc.

[Michael Miller]

Not compatible with latest version of Matlab (R2007a). The following error occurs even when you run the demo.
>> es_demo
??? There is no 'UIContextMenu' property in the 'com.mathworks.hg.peer.UITreeNode' class.

Error in ==> explorestruct at 83
set(root,'UIContextMenu', cmenu);

83 set(root,'UIContextMenu', cmenu);

[Eric Lee]

A good tool!
Note: I made a small change to line 182, to avoid the need to copy the exp_struct_icons directory. This may make the tool more portable.

% pth = [matlabroot, '\work\exp_struct_icons\'];
pth = [fileparts(mfilename('fullpath')) '\exp_struct_icons\']

Suppose, the tree is huge and if i provide the user to enter the text in editbox and a search button to search for the text.And on click of the search button, if the entered text is present in the tree, then that Node has to be highlighted.How can this functionlity be achieved?

[Jagadeesh K]

How to highlight a particular node of the tree?
or
How to setfocus on a particular node of the tree?

[Martin Römpert]

Excellent tool ...

Change line 83 ff to:
% set(root,'UIContextMenu', cmenu);
t = tree.Tree;
set(t,'UIContextMenu', cmenu)

[Michael Ashby]

I am unable to get this to work, even on the demo.

The GUI is displayed but is missing the left side completely. No error messages. I am running 2008a.

Any advice please?

[Michael Ashby]

add to comment above...

Matlab version 7.7.0

Thanks

[Tobias Nüesch]

I've got the same problems as Michael Ashby in R2008b (7.7.0.471): the left side is missing.

Does anyone have a fixed version?

[Tobias Nüesch]

Got it for R2008b!

First, add 'v0' to the uitreenode and uitree commands. Second, pause the execution of the m-file after the uitree command by approx. 0.1 seconds (could depend on your computer). To this, replace the code from line 28 to 31 by

set(h, 'Name', fig_name);
root = uitreenode('v0', name, name, [], false);
tree = uitree('v0', 'Root', root, 'ExpandFcn', @myExpfcn4);
pause(0.1)
set(tree, 'Units', 'normalized', 'position', [0 0 0.35 1]);

[Michael Ashby]

So, with Tobias' fix (above), this is working nicely. Thanks to the author and to Tobias.

[Aurelien Queffurust]

It also works in R2009a when you modify the lines 28 to 31
You have to add a first argument 'v0' to line 83 as mentionned Martin Römpert ... but also for EACH line with uitreenode . It will prevent warnings in a standalone mode (MATLAB Compiler). These warnings tell you to add v0 to continue to use this undocumnted feature (uitreenode). I made this modification and now there is no warning at all when I expand my nodes.

Hassan,

Extremely nice tool!
There is a tiny bug in the subfunction getcNodevalue.
Replace
d = findstr(field,'(');
and
idx = str2num(field(d+1));

with
        d = findstr(field,'(');
        d_e = findstr(field,')');
            idx = str2num(field(d+1:d_e-1));

as else the structure will not correctly refresh for structures >(9*1).

Best regards,
Patrice
