10 Examples of GUIDE GUIs

• Creates a structure to save the results of the simulation, the current

values of the simulation parameters set by the GUI, and the run name

and number.

• Stores the structure in the

handles structure.

• Updates the list box

String to list the most recent run.

Here is the Simulate and store results button callback:

function Simula teBu tton_Callback(hObject, eventdata, handles)

[timeVector,stateVector,outputVecto r] = sim('f14');

% Retrieve old results data structure

if isfield(h andl es,'ResultsData') &

~isempty(handles.ResultsData)

ResultsData = handles.ResultsData;

% Determine the maximum run number currently used.

maxNum = ResultsData(length(Result sData)).RunNumber;

ResultNum = maxNum+1;

else % Set up the results data structure

ResultsData = struct('RunName',[],'RunNumber',[],...

'KiValue',[],'KfValue',[],'timeVector ',[],...

'outputVector',[]);

ResultNum = 1;

end

if isequal(R esul tNum,1),

% Enable the Plot and Remove buttons

set([handles.RemoveButton,handles.Plot Button],'Enable','on')

end

% Get Ki and Kf values to store with the data and put in the

results list .

Ki = get(handles.KiValueSlider, 'Value');

Kf = get(handles.KfValueSlider, 'Value');

ResultsData(ResultNum).RunName = ['Run',num2str(Result Num)];

ResultsData(ResultNum).RunNumber = ResultNum;

ResultsData(ResultNum).KiValue = Ki;

ResultsData(ResultNum).KfValue = Kf;

ResultsData(ResultNum).timeVector = timeVector;

ResultsData(ResultNum).outputVector = outputVector;

% Build the new results lis t string for the listbox

ResultsStr = get(handles.ResultsList,'String');
