将单选按钮中的值传递到Matlab中的脚本中

因此，我在指南中创建了如下GUI：

我想从单选按钮访问数据，然后在模拟中更改变量（比特率和调制是按钮组，改进是单个单选按钮）。例如，在模拟中，我有一个变量

Rs=1e9

，因此当选择1Gbps按钮时，我希望它保持1e9，但如果选择10Gbps按钮，我希望它将其值更改为10e9

然后在点击开始按钮后，我想用给定的参数开始我的模拟（在不同的.m文件中）我该怎么做？（我知道matlab中的handles思想，但我不知道如何将值传递给仿真）

这是控制guide生成的gui的代码。我添加了一些启动模拟并关闭gui窗口的代码

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

您可以使用对象“hObject”来执行此操作

这样：假设您有一个滑块，每次移动滑块时都会调用回调。您可以使用它来存储变量。然后，当你按下一个按钮，你想用这些数据做任何事情。代码是：

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

更新

在你的情况下，如果你愿意，你可以用另一种方法。当你按下“开始”按钮时，你会读取单选按钮的状态，并将适当的值传递给你的simulation_函数，我想它被称为“simulation”。在下面的示例中，我假设您有一个名为（tag）的按钮组：uibuttongroup1，其中有两个按钮：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)');

很抱歉，我仍然不明白如何通过模拟将此数据传递到脚本。确定。我忘了写我的脚本不是函数。所以我把它转换成一个函数。但是使用您的代码我得到了另一个错误：

switch get（get（handles.Bitrate，'SelectedObject'），'Tag'）case'onegbps'，Bitrate=1e9；案例'tengbps'，比特率=10e9；end message=sprintf（'等待-这是一个很长的模拟！\n单击“确定”按钮并等待'）；uiwait（msgbox（message））；evalin（“基本”、“模拟（比特率、调制、真）”。错误：
使用evalin未定义函数或变量“bitrate”时出错。
好的，我更正了您的答案-evalin（'base'，['simulation（'num2str（bitrate）'））@dawzaw您不需要使用“evalin”。如果在.m文件中有模拟函数，则可以这样调用：message=sprintf（'等待-这是一个很长的模拟！\n单击“确定”按钮并等待'）；uiwait（msgbox（message））；模拟（myParameter）；
