[英]How do I get the path from MATLAB?
I want to implement a GUI environment in MATLAB. 我想在MATLAB中实现GUI环境。 I want to use the Browser button to load a file, then input the file into the code I want to use and output it. 我想使用“浏览器”按钮加载文件,然后将文件输入到要使用的代码中并输出。 Help. 救命。
% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(~, ~, 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)
[filename, pathname] = uigetfile({'*.txt'},'File Selector');
fullpathname = strcat(pathname, filename);
text = fileread(fullpathname);
set(handles.text2, 'String', fullpathname)
% --- Executes on button press in pushbutton2.
function pushbutton2_Callback(~, ~, 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)
[filename, pathname] = uigetfile({'*.txt'},'File Selector');
fullpathname = strcat(pathname, filename);
text = fileread(fullpathname);
set(handles.text3, 'String', fullpathname)
% --- Executes on button press in pushbutton3.
function pushbutton3_Callback(~, ~, handles)
% hObject handle to pushbutton3 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
[filename, pathname] = uigetfile({'*.txt'},'File Selector');
fullpathname = strcat(pathname, filename);
text = fileread(fullpathname);
set(handles.text4, 'String', fullpathname)
D1=load('text2');
D1=D1';
D1=reshape(D1,l1*l2,1);
%% D2,D3 매트릭스 direct데이터 파일
D2=load('text3');
D3=load('text4');
You used 你用过
set(handles.text2, 'String', fullpathname)
so in the routine that needs the name, you can use 因此在需要名称的例程中,您可以使用
get(handles.text2, 'String')
All three of your callbacks already do exactly what you want to do: 您的所有三个回调已经完全完成了您想做的事情:
fullpathname
variable 他们将路径保存在fullpathname
变量中 String
property of the handles text2
, text3
or text4
. 他们将文本分配给句柄text2
, text3
或text4
的String
属性。 So now there are several reasons why this could fail to work as you expect: 因此,现在有几个原因导致此操作无法按预期工作的原因:
text2
, text3
or text4
exist. 句柄text2
, text3
或text4
存在。 So Matlab does not know where to assign the text. 因此Matlab不知道在哪里分配文本。 You can get a overview of all elements by using the Object browser in the upper menu: 您可以使用上方菜单中的“对象”浏览器来获得所有元素的概述: fileread
is not able to read the content of your files. fileread
无法读取文件的内容。 You could check this by making sure fileread
is working on your files with a simple non-GUI script. 您可以通过使用简单的非GUI脚本确保fileread
在文件上正常工作来进行检查。
