将上述代码的gui代码写出来

好的，下面是一个简单的 MATLAB GUI 代码，实现了将彩色图像转换为黑白图像的功能：

function varargout = color2bw_gui(varargin)
% COLOR2BW_GUI MATLAB code for color2bw_gui.fig
%      COLOR2BW_GUI, by itself, creates a new COLOR2BW_GUI or raises the existing
%      singleton*.
%
%      H = COLOR2BW_GUI returns the handle to a new COLOR2BW_GUI or the handle to
%      the existing singleton*.
%
%      COLOR2BW_GUI('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in COLOR2BW_GUI.M with the given input arguments.
%
%      COLOR2BW_GUI('Property','Value',...) creates a new COLOR2BW_GUI or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before color2bw_gui_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to color2bw_gui_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".

% --- Executes just before color2bw_gui is made visible.
function color2bw_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 color2bw_gui (see VARARGIN)

% Choose default command line output for color2bw_gui
handles.output = hObject;

% Update handles structure
guidata(hObject, handles);

% UIWAIT makes color2bw_gui wait for user response (see UIRESUME)
% uiwait(handles.figure1);


% --- Outputs from this function are returned to the command line.
function varargout = color2bw_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 pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% 读取彩色图像
[filename, pathname] = uigetfile({'*.jpg;*.jpeg;*.png;*.bmp;*.gif','All Image Files'}, 'Select an Image File');
if isequal(filename,0) || isequal(pathname,0)
    return;
end
rgbImage = imread(fullfile(pathname, filename));

% 将彩色图像转换为灰度图像
grayImage = rgb2gray(rgbImage);

% 将灰度图像保存为黑白图像
bwImage = imbinarize(grayImage, 0.5);

% 显示原始彩色图像和转换后的黑白图像
axes(handles.axes1);
imshow(rgbImage);
title('Original Color Image');
axes(handles.axes2);
imshow(bwImage);
title('Converted Black and White Image');


% --- Executes on button press in pushbutton2.
function pushbutton2_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton2 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% 关闭GUI窗口
close(handles.figure1);

此代码使用 MATLAB 的 GUI 设计工具 GUIDE 生成，包含两个按钮和两个图像显示区域。当用户点击“打开图像”按钮时，程序会弹出一个文件选择对话框，让用户选择要转换的彩色图像文件。程序将选择的彩色图像转换为灰度图像和黑白图像，并分别显示在两个图像显示区域中。当用户点击“关闭”按钮时，程序会关闭 GUI 窗口。
