This comment describes that mechanism. 40 | %| 41 | %| Each callback subfunction declaration has the following form: 42 | %| (H, EVENTDATA, HANDLES, VARARGIN) 43 | %| 44 | %| The subfunction name is composed using the object's Tag and the 45 | %| callback type separated by '_', e.g. 'slider2_Callback', 46 | %| 'figure1_CloseRequestFcn', 'axis1_ButtondownFcn'. 47 | %| 48 | %| H is the callback object's handle (obtained using GCBO). 49 | %| 50 | %| EVENTDATA is empty, but reserved for future use. 51 | %| 52 | %| HANDLES is a structure containing handles of components in GUI using 53 | %| tags as fieldnames, e.g. handles.figure1, handles.slider2. This 54 | %| structure is created at GUI startup using GUIHANDLES and stored in 55 | %| the figure's application data using GUIDATA. A copy of the structure 56 | %| is passed to each callback. You can store additional information in 57 | %| this structure at GUI startup, and you can change the structure 58 | %| during callbacks. Call guidata(h, handles) after changing your 59 | %| copy to replace the stored original so that subsequent callbacks see 60 | %| the updates. Type "help guihandles" and "help guidata" for more 61 | %| information. 62 | %| 63 | %| VARARGIN contains any extra arguments you have passed to the 64 | %| callback. Specify the extra arguments by editing the callback 65 | %| property in the inspector. By default, GUIDE sets the property to: 66 | %| ('', gcbo, [], guidata(gcbo)) 67 | %| Add any extra arguments after the last argument, before the final 68 | %| closing parenthesis. 69 | 70 | 71 | % -------------------------------------------------------------------- 72 | %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% 73 | % Callback to open and read a file. 74 | %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% 75 | function varargout = FileOpen1_Callback(h, eventdata, handles, varargin) 76 | 77 | % Get file name 78 | [filename,path] = uigetfile('*.dat','Load Data File'); 79 | if filename ~= 0 80 | 81 | % Read data 82 | x = textread([path filename],'%f'); 83 | 84 | % Save in handles structure 85 | handles.x = x; 86 | guidata(gcbf, handles); 87 | 88 | % Create histogram 89 | hist(handles.x,handles.nbins); 90 | 91 | % Set axis labels 92 | xlabel('\bfValue'); 93 | ylabel('\bfCount'); 94 | 95 | % Calculate statistics 96 | ave = mean(x); 97 | med = median(x); 98 | sd = std(x); 99 | n = length(x); 100 | 101 | % Update fields 102 | set (handles.MeanData,'String',sprintf('%7.2f',ave)); 103 | set (handles.MedianData,'String',sprintf('%7.2f',med)); 104 | set (handles.StdDevData,'String',sprintf('%7.2f',sd)); 105 | set (handles.TitleString,'String',['Histogram (N = ' int2str(n) ')']); 106 | 107 | end 108 | 109 | 110 | %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% 111 | % Callback to exit. 112 | %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% 113 | function varargout = FileExit1_Callback(h, eventdata, handles, varargin) 114 | close(gcbf); 115 | 116 | %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% 117 | % Callback to set number of bins. 118 | %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% 119 | function varargout = NBins_Callback(h, eventdata, handles, varargin) 120 | 121 | % Get number of bins, round to integer, and update field 122 | nbins = str2num(get(gcbo,'String')); 123 | nbins = round(nbins); 124 | if nbins < 1 125 | nbins = 1; 126 | end 127 | set (handles.NBins,'String',int2str(nbins)); 128 | 129 | % Save in handles structure 130 | handles.nbins = nbins; 131 | guidata(gcbf, handles); 132 | 133 | % Re-display data, if available 134 | if handles.nbins > 0 & ~isempty(handles.x) 135 | 136 | % Create histogram 137 | hist(handles.x,handles.nbins); 138 | 139 | end 140 | 141 | 142 | -------------------------------------------------------------------------------- /assets/《Matlab编程》源码/chap10/MyFirstGUI/MyFirstGUI.fig: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/101Hub/Matlab101/07273f68f1147a110443aeb121fa10962234f298/assets/《Matlab编程》源码/chap10/MyFirstGUI/MyFirstGUI.fig -------------------------------------------------------------------------------- /assets/《Matlab编程》源码/chap10/MyFirstGUI/MyFirstGUI.m: -------------------------------------------------------------------------------- 1 | function varargout = MyFirstGUI(varargin) 2 | % MYFIRSTGUI M-file for MyFirstGUI.fig 3 | % MYFIRSTGUI, by itself, creates a new MYFIRSTGUI or raises the existing 4 | % singleton*. 5 | % 6 | % H = MYFIRSTGUI returns the handle to a new MYFIRSTGUI or the handle to 7 | % the existing singleton*. 8 | % 9 | % MYFIRSTGUI('CALLBACK',hObject,eventData,handles,...) calls the local 10 | % function named CALLBACK in MYFIRSTGUI.M with the given input arguments. 11 | % 12 | % MYFIRSTGUI('Property','Value',...) creates a new MYFIRSTGUI or raises the 13 | % existing singleton*.

This comment describes that mechanism. 35 | %| 36 | %| Each callback subfunction declaration has the following form: 37 | %| (H, EVENTDATA, HANDLES, VARARGIN) 38 | %| 39 | %| The subfunction name is composed using the object's Tag and the 40 | %| callback type separated by '_', e.g. 'slider2_Callback', 41 | %| 'figure1_CloseRequestFcn', 'axis1_ButtondownFcn'. 42 | %| 43 | %| H is the callback object's handle (obtained using GCBO). 44 | %| 45 | %| EVENTDATA is empty, but reserved for future use. 46 | %| 47 | %| HANDLES is a structure containing handles of components in GUI using 48 | %| tags as fieldnames, e.g. handles.figure1, handles.slider2. This 49 | %| structure is created at GUI startup using GUIHANDLES and stored in 50 | %| the figure's application data using GUIDATA. A copy of the structure 51 | %| is passed to each callback. You can store additional information in 52 | %| this structure at GUI startup, and you can change the structure 53 | %| during callbacks. Call guidata(h, handles) after changing your 54 | %| copy to replace the stored original so that subsequent callbacks see 55 | %| the updates. Type "help guihandles" and "help guidata" for more 56 | %| information. 57 | %| 58 | %| VARARGIN contains any extra arguments you have passed to the 59 | %| callback. Specify the extra arguments by editing the callback 60 | %| property in the inspector. By default, GUIDE sets the property to: 61 | %| ('', gcbo, [], guidata(gcbo)) 62 | %| Add any extra arguments after the last argument, before the final 63 | %| closing parenthesis. 64 | 65 | 66 | 67 | % -------------------------------------------------------------------- 68 | function varargout = pushbutton1_Callback(h, eventdata, handles, varargin) 69 | % Stub for Callback of the uicontrol handles.pushbutton1. 70 | disp('pushbutton1 Callback not implemented yet.') 71 | 72 | 73 | % -------------------------------------------------------------------- 74 | function varargout = togglebutton1_Callback(h, eventdata, handles, varargin) 75 | % Stub for Callback of the uicontrol handles.togglebutton1. 76 | disp('togglebutton1 Callback not implemented yet.') 77 | 78 | 79 | % -------------------------------------------------------------------- 80 | function varargout = radiobutton1_Callback(h, eventdata, handles, varargin) 81 | % Stub for Callback of the uicontrol handles.radiobutton1. 82 | disp('radiobutton1 Callback not implemented yet.') 83 | 84 | 85 | % -------------------------------------------------------------------- 86 | function varargout = checkbox1_Callback(h, eventdata, handles, varargin) 87 | % Stub for Callback of the uicontrol handles.checkbox1. 88 | disp('checkbox1 Callback not implemented yet.') 89 | 90 | 91 | % -------------------------------------------------------------------- 92 | function varargout = edit1_Callback(h, eventdata, handles, varargin) 93 | % Stub for Callback of the uicontrol handles.edit1. 94 | disp('edit1 Callback not implemented yet.') 95 | 96 | 97 | % -------------------------------------------------------------------- 98 | function varargout = slider1_Callback(h, eventdata, handles, varargin) 99 | % Stub for Callback of the uicontrol handles.slider1. 100 | disp('slider1 Callback not implemented yet.') 101 | 102 | 103 | % -------------------------------------------------------------------- 104 | function varargout = listbox1_Callback(h, eventdata, handles, varargin) 105 | % Stub for Callback of the uicontrol handles.listbox1. 106 | disp('listbox1 Callback not implemented yet.') 107 | 108 | 109 | % -------------------------------------------------------------------- 110 | function varargout = radiobutton3_Callback(h, eventdata, handles, varargin) 111 | % Stub for Callback of the uicontrol handles.radiobutton3. 112 | disp('radiobutton3 Callback not implemented yet.') 113 | 114 | 115 | % --- Executes on button press in radiobutton2. 116 | function radiobutton2_Callback(hObject, eventdata, handles) 117 | % hObject handle to radiobutton2 (see GCBO) 118 | % eventdata reserved - to be defined in a future version of MATLAB 119 | % handles structure with handles and user data (see GUIDATA) 120 | 121 | % Hint: get(hObject,'Value') returns toggle state of radiobutton2 122 | 123 | 124 | -------------------------------------------------------------------------------- /assets/《Matlab编程》源码/chap9/plotsinc.m: -------------------------------------------------------------------------------- 1 | % Script file: plotsinc.m 2 | % 3 | % Purpose: 4 | % This program illustrates the use of handle graphics 5 | % commands by creating a plot of sinc(x) from -3*pi to 6 | % 3*pi, and modifying the characteristics of the figure, 7 | % axes, and line using the "set" function. 8 | % 9 | % Record of revisions: 10 | % Date Programmer Description of change 11 | % ==== ========== ===================== 12 | % 04/02/07 S.
