matlab通过gui界面在编辑注册界面时输入名字的正确代码

以下是一个简单的 MATLAB GUI 界面,其中包括一个文本输入框和一个按钮,可以在文本框中输入名字,并将其打印到 MATLAB 命令窗口中。
```matlab
function varargout = register_gui(varargin)
% REGISTER_GUI MATLAB code for register_gui.fig
% REGISTER_GUI, by itself, creates a new REGISTER_GUI or raises the existing
% singleton*.
%
% H = REGISTER_GUI returns the handle to a new REGISTER_GUI or the handle to
% the existing singleton*.
%
% REGISTER_GUI('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in REGISTER_GUI.M with the given input arguments.
%
% REGISTER_GUI('Property','Value',...) creates a new REGISTER_GUI or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before register_gui_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to register_gui_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".

% Begin initialization code - DO NOT EDIT
gui_Singleton = 1;
gui_State = struct('gui_Name', mfilename, ...
'gui_Singleton', gui_Singleton, ...
'gui_OpeningFcn', @register_gui_OpeningFcn, ...
'gui_OutputFcn', @register_gui_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 register_gui is made visible.
function register_gui_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 command line arguments to register_gui (see VARARGIN)
% Choose default command line output for register_gui
handles.output = hObject;
% Update handles structure
guidata(hObject, handles);
% UIWAIT makes register_gui wait for user response (see UIRESUME)
% uiwait(handles.figure1);
% --- Outputs from this function are returned to the command line.
function varargout = register_gui_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 register_button.
function register_button_Callback(hObject, eventdata, handles)
% hObject handle to register_button (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
% Read the string from the text input box
name = get(handles.name_input, 'String');
% Print the name to the MATLAB command window
disp(['Name: ' name]);
function name_input_Callback(hObject, eventdata, handles)
% hObject handle to name_input (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
% Hints: get(hObject,'String') returns contents of name_input as text
% str2double(get(hObject,'String')) returns contents of name_input as a double
% --- Executes during object creation, after setting all properties.
function name_input_CreateFcn(hObject, eventdata, handles)
% hObject handle to name_input (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles empty - handles not created until after all CreateFcns called
% Hint: edit controls usually have a white background on Windows.
% See ISPC and COMPUTER.
if ispc && isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor'))
set(hObject,'BackgroundColor','white');
end
```
在这个 GUI 界面中,名字输入框的句柄为 `name_input`,注册按钮的句柄为 `register_button`。在 `register_button_Callback` 回调函数中,使用 `get` 函数获取名字输入框中的字符串,并使用 `disp` 函数将其打印到 MATLAB 命令窗口中。
