Question

我是Matlab的新手，请在这个问题上指导我。我有两个数字，我想将数据从第一个数字传递到第二个数字。代码：

function pushbutton1_Callback(hObject, eventdata, handles)
    tryText=get(handles.text2,'String');
    open SecondPage.fig
guidata(hObject,handles);

如何在＆＃34; tryText＆＃34;中传递数据？并在第二个图中使用它？

我尝试使用以下格式传递数据：

function pushbutton1_Callback(hObject, eventdata, handles)
    tryText=get(handles.text2,'String');
    SecondPage(tryText)
guidata(hObject,handles);

但我没有运气检索它。感谢

最新更新：

function varargout = first(varargin)
handles=struct;
datas=struct;
    gui_Singleton = 1;
    gui_State = struct('gui_Name',       mfilename, ...
                       'gui_Singleton',  gui_Singleton, ...
                       'gui_OpeningFcn', @first_OpeningFcn, ...
                       'gui_OutputFcn',  @first_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

function first_OpeningFcn(hObject, eventdata, handles, varargin)
     handles.output = hObject;
guidata(hObject, handles);

function varargout = first_OutputFcn(hObject, eventdata, handles) 

varargout{1} = handles.output;

function pushbutton1_Callback(hObject, eventdata, handles)
    struct.a=get(handles.edit1,'String');
        set(handles.text1,'String',struct.a);
        disp(struct);
    setappdata(0,'MyStruct',struct);
open second.fig

在第二时的意思是：

function varargout = second(varargin)
    getappdata(0,'MyStruct');
        gui_Singleton = 1;
        gui_State = struct('gui_Name',       mfilename, ...
                       'gui_Singleton',  gui_Singleton, ...
                       'gui_OpeningFcn', @second_OpeningFcn, ...
                       'gui_OutputFcn',  @second_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


function second_OpeningFcn(hObject, eventdata, handles, varargin)
    handles.output = hObject;
guidata(hObject, handles);

function varargout = second_OutputFcn(hObject, eventdata, handles) 

varargout{1} = handles.output;


function pushbutton1_Callback(hObject, eventdata, handles)
disp(struct)

在第一个图中，disp（struct）的结果是正确的，而在第二个图中，它显示了没有字段的＆＃34; 1x1结构数组。＆＃34;
有人能突出我的错误吗？感谢

Answer 1

您需要使用句柄和数据结构来执行此操作。我将简单地指向an answer given in MATLAB Central，而不是向您展示如何在此处执行此操作，而是告诉您如何实现此目标。

感谢您的回复，我终于设法使用以下代码。

代码：

  function varargout = second(varargin)

    gui_Singleton = 1;
    gui_State = struct('gui_Name',       mfilename, ...
                   'gui_Singleton',  gui_Singleton, ...
                   'gui_OpeningFcn', @second_OpeningFcn, ...
                   'gui_OutputFcn',  @second_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


function second_OpeningFcn(hObject, eventdata, handles, varargin)
    handles.output = hObject;
guidata(hObject, handles);

function varargout = second_OutputFcn(hObject, eventdata, handles) 

varargout{1} = handles.output;


function pushbutton1_Callback(hObject, eventdata, handles)
    struct=getappdata(0,'MyStruct');
disp(struct)

Matlab将数据传递到另一个GUI
