MATLAB: Simulink_and gui and figure

figureguisignal processingsimulink

hello, i have a big problem ……. i make project in simulink this project has input values which related with component which i use ,and i have 3 scopes ,so i want to make gui which simulate this simulink project and output of scopes will appear in figure in gui and use edit texts to adjust input values of project so what i need is: 1-how to connect simulink with gui file and how gui file identify the parts used in simulink 2-how can i show scope in gui figure 3-how can i adjust input of component by writing value in edit text many thanks

You can use event listener to make communication between your GUI and simulink.

See

add_exec_event_listener,

How can I update a GUI with values from my Simulink model as it is running?.

You can start from a good example located here

MATLAB: How to update a GUI with values from the Simulink model as it is running

There is no direct way to access the runtime parameters of a Simulink model from a MATLAB GUI. To work around this issue, you need to create a function that will update the GUI with the desired model data at each time step. An outline of this procedure is as follows.

1. Create a GUI with a control that you would like to update with information from the model. In this example, we would like to see the output of the model's Gain block in the GUIs edit text window.

2. Create a model callback function that will register an event listener for the block in question. This function will be called every time the block is updated. We will use it to access the value of the Gain blocks output and pass them to the GUI. In this case we will use the models 'StartFcn' callback.

%The GUI handles are by default hidden, turn them on
set(0,'ShowHiddenHandles','on');
%Set up the arguments that will go into the gain block event callback listener
blk = 'mytestmdl/Gain';
event = 'PostOutputs';
listener = @updategui;
%Create the listener
h = add_exec_event_listener(blk, event, listener);

3. Create a MATLAB file function that will get the Gain block's runtime output parameter and pass it to the GUI.

function varargout = updategui(varargin)
%create a run time object that can return the value of the gain block's
%output and then put the value in a string.  
rto = get_param('mytestmdl/Gain','RuntimeObject');
str = num2str(rto.OutputPort(1).Data);
%get a handle to the GUI's 'current state' window
statestxt = findobj('Tag','curState');
%update the gui
set(statestxt,'string',str);

The standard "Callback". It has no other name. To set it, right-click in GUIDE - View Callbacks - Callback
