傳遞從單選按鈕值到腳本在Matlab

Question

所以我指導，看起來像這樣創建GUI：

GUI

我想從單選按鈕來訪問數據，然後改變我的模擬變量（比特率和調製是按鈕組，改進是單個單選按鈕）。例如 - 在模擬中，我有一個變量Rs=1e9，所以當選擇1Gbps按鈕時，我希望它保持1e9，但是如果選擇10Gbps按鈕，我希望它將其值更改爲10e9。

然後在點擊開始按鈕之後，我想用給定的參數開始我的仿真（在不同的.m文件中）。 我該怎麼辦？（我知道matlab中的句柄思想，但我不知道如何將值傳遞給模擬）

這是控制gui的代碼 - 由指南生成。我添加了一些開始模擬並關閉gui窗口的代碼。

function varargout = gui_final(varargin) 


% Begin initialization code - DO NOT EDIT 
gui_Singleton = 1; 
gui_State = struct('gui_Name',  mfilename, ... 
        'gui_Singleton', gui_Singleton, ... 
        'gui_OpeningFcn', @gui_final_OpeningFcn, ... 
        'gui_OutputFcn', @gui_final_OutputFcn, ... 
        'gui_LayoutFcn', [], ... 
        'gui_Callback', []); 
if nargin && ischar(varargin{1}) 
    gui_State.gui_Callback = str2func(varargin{1}); 
end 

if nargout 
    [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:}); 
else 
    gui_mainfcn(gui_State, varargin{:}); 
end 
% End initialization code - DO NOT EDIT 


% --- Executes just before gui_final is made visible. 
function gui_final_OpeningFcn(hObject, eventdata, handles, varargin) 
% This function has no output args, see OutputFcn. 
% hObject handle to figure 
% eventdata reserved - to be defined in a future version of MATLAB 
% handles structure with handles and user data (see GUIDATA) 
% varargin unrecognized PropertyName/PropertyValue pairs from the 
%   command line (see VARARGIN) 

% Choose default command line output for gui_final 
handles.output = hObject; 

% Update handles structure 
guidata(hObject, handles); 

% UIWAIT makes gui_final wait for user response (see UIRESUME) 
% uiwait(handles.figure1); 


% --- Outputs from this function are returned to the command line. 
function varargout = gui_final_OutputFcn(hObject, eventdata, handles) 
% varargout cell array for returning output args (see VARARGOUT); 
% hObject handle to figure 
% eventdata reserved - to be defined in a future version of MATLAB 
% handles structure with handles and user data (see GUIDATA) 

% Get default command line output from handles structure 
varargout{1} = handles.output; 


% --- Executes on button press in start. 
function start_Callback(hObject, eventdata, handles) 
% hObject handle to start (see GCBO) 
% eventdata reserved - to be defined in a future version of MATLAB 
% handles structure with handles and user data (see GUIDATA) 
clc 
close all 

message = sprintf('Wait - this is a very long simulation!\nClick the OK button and wait'); 
uiwait(msgbox(message)); 
evalin('base', 'simulation'); 


% --- Executes on button press in dfe. 
function dfe_Callback(hObject, eventdata, handles) 
% hObject handle to dfe (see GCBO) 
% eventdata reserved - to be defined in a future version of MATLAB 
% handles structure with handles and user data (see GUIDATA) 

% Hint: get(hObject,'Value') returns toggle state of dfe 


% --- Executes on button press in ook. 
function ook_Callback(hObject, eventdata, handles) 
% hObject handle to ook (see GCBO) 
% eventdata reserved - to be defined in a future version of MATLAB 
% handles structure with handles and user data (see GUIDATA) 

% Hint: get(hObject,'Value') returns toggle state of ook

您可以使用對象「hObject」

篩選做到這一點：假設你有一個滑，每次移動滑塊回調被調用。你可以用它來存儲一個變量。然後，當你按下一個按鈕時，你想使用這些數據。該代碼是：

function slider_callback(hObject,eventdata) 
    sval = hObject.Value; 
    diffMax = hObject.Max - sval; 
    data = struct('val',sval,'diffMax',diffMax); 
    hObject.UserData = data; 
    % For R2014a and earlier: 
    % sval = get(hObject,'Value'); 
    % maxval = get(hObject,'Max'); 
    % diffMax = maxval - sval;  
    % data = struct('val',sval,'diffMax',diffMax); 
    % set(hObject,'UserData',data); 

end 

function button_callback(hObject,eventdata) 
    h = findobj('Tag','slider1'); 
    data = h.UserData; 
    % For R2014a and earlier: 
    % data = get(h,'UserData'); 
    display([data.val data.diffMax]); 
end

UPDATE

你的情況，你可以用另一種方法做，如果你想要的。當您按下按鈕START時，您將讀取單選按鈕的狀態，並將相應的值傳遞給您的simulation_function，我認爲它被稱爲「模擬」。在下面的例子中，我假設你有一個名爲（標籤）按鈕組：uibuttongroup1了，裏面有兩個按鈕：radiobutton1和radiobutton2

% --- Executes on button press in start. 
function start_Callback(hObject, eventdata, handles) 
% hObject handle to start (see GCBO) 
% eventdata reserved - to be defined in a future version of MATLAB 
% handles structure with handles and user data (see GUIDATA) 

%Check which radio button is pressed 
switch get(get(handles.uibuttongroup1,'SelectedObject'),'Tag') 
    case 'radiobutton1', myParameter = 1e9; 
    case 'radiobutton2', myParameter = 10e9; 
end 
%Execute simulation 
clc 
close all 

message = sprintf('Wait - this is a very long simulation!\nClick the OK button and wait'); 
uiwait(msgbox(message)); 
evalin('base', 'simulation(myParameter)');
