Question

我是matlab的新手，我正在尝试在列表框中加载多个文件。到目前为止我有这个代码，但它告诉我这个错误：输入了无关的参数，请查看文档。这就是我所拥有的代码：

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

[flnm, flpth,cCheck]=uigetfile({'*.mp3'},...
                            'File Select',...
                            'Multiset', 'on');
 %fullpathname=strcat(pathname, filename);
 %text=audioread(fullpathname);
 %set(handles.path_song, 'String',fullpathname);%show full path name in the listbox

 assignin('base','flnm',flnm);
 assignin('base','flpth',flpth);
 assignin('base','cCheck',cCheck);

 %If the user did not press the cancell button
if(cCheck==0)
%Reset selection to first entry
set(handles.playlist,'Value',1);
%Show selected filenames
set(handles.playlist,'String',flnm);
end
%LIST------------------------Display Files---------------------------------

function playlist_Callback(hObject, eventdata, handles)
% hObject    handle to playlist (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% Hints: contents = cellstr(get(hObject,'String')) returns playlist contents    as cell array
%        contents{get(hObject,'Value')} returns selected item from playlist  

listStr=get(hObject,'String');
listVal=get(hObject,'Value');

%Display Selected files
if(iscell(listStr))
   fileName=playlistStr(listVal);
   fprintf('Selected file:%s\n',fileName);
else
   fileName=listStr;
   fprintf('Selected file:%s\n',fileName);
end

Answer 1

您的代码中存在一些错误：

在load_Callback cllback

在致电uigetfile时有一个错字：有问题的Multiset应为Multiselect
测试if(cCheck==0)应为if(cCheck)：如果用户按下Open按钮，则uigetfile会返回1

playlist_Callback

修正上述错误，两个回调结果：

cell

希望这有帮助，
