MATLAB: How to a GUI directly in Simulink Model

matlab guisimulink

Is it possible to display a GUI directly in a Simulink model ?

The GUI can be used for entering values or for selection of Variables before simulation. What it avoids is the double click required to open the GUI and shows the selected parameters.

Best Answer

You can invoke a gui from a block. Create an empty subsystem. In its open function, you can call the GUI. In the GUI you can set all the parameters in one window and then start the simulation.

MATLAB: How to clear MATLAB Workspace directly through App designer

The problem solved by creating a Simulink file which simply contains a callback function to clear the workspace. Then I added a code to recall this model at the end of my run script to erase everything before the next run.

MATLAB: Directly open custom documentation

It hasn't bothered me, but

doc toolbox_name

If the name is unique enough it produces a short list of search results. In my case the page of interest is the top one. One extra click needed.

Next a one-liner, which opens the documentation home page in the help browser (using a bit of magic)

web('documentation_home_page.html','-new')

However, this must be hidden from the user in one way or another and still be easy to use. A favorite doesn't really provide much of an improvement.

In response to comment

The magic works better for me

>> web('m2umlToolbox.html', '-new')

produces this

The function, builtin, doesn't work with doc, but How do I invoke a shadowed core MATLAB function does. Now

doc m2uml

opens the page shown above and

doc plot

opens the expected Matlab page.

Listing of doc

function    doc( varargin )
    
    persistent mdc
    if isempty( mdc )
      wch = which('doc.m','-all'); 
      isf = contains( wch, matlabroot ); % there should only be one
      wch = wch{isf};
      pth = fileparts( wch );
      old = cd( pth ); 
      mdc = str2func('doc');  % create a function-handle
      cd( old ); 
    end    
    
    switch varargin{1}
        case 'm2uml'
            web('m2umlToolbox.html', '-new')
        otherwise
            mdc( varargin{:} )
    end
end

Files and search path

I've used the word "magic" a couple of times to indicate that I don't understand how it works or what's required to make it work. I've stumbled upon one way that hasn't failed so far.

My starting point was the blog, Best Practices – Adapt, then Adopt! Posted by Andy Campbell, January 13, 2017 , which predates my R2018b. This blog "presents" the FEX-submission, Toolbox Tools 1.1 by Amy Koh, [Staff], A toolbox for developing custom toolboxes in MATLAB. This toolbox was "Created with R2017b" and is "Compatible with any release".

Important files, i.e files which I beleive are required

...\tbx\info.xml where tbx is on the search path. Used by Matlab to find the documentation (i.e. create some kind of database entry)
...\tbx\doc\helptoc.xml where doc is on the search path.
...\tbx\doc\*.html all the html-files

where info.xml (there must be exactly one info.xml with the name-tag-value m2uml)

        <tocitem target="Examples.html">                Examples                </tocitem>
        <tocitem target="TechnicalDocumentation.html">  Technical documentation </tocitem>
    </tocitem>
</toc>

It seems, it doesn't matter which html-file (in the folder, doc) I open

>> web('ImageRow.html','-new')

works as I have come to expect (i.e. navigation panel to the left).
