function listbox1_Callback(hObject, eventdata, handles)

list = get(hObject,'String');
item_selected = list{index_selected}; % Convert from cell array % to string
 disp(item_selected);

 GetColumnC(handles, textdata);




function listbox2_Callback(hObject, eventdata, handles)
index_selected = get(hObject,'Value');
list = get(hObject,'String');
item_selected2 = list{index_selected}; % Convert from cell array
                                      % to string
disp(item_selected2);
 textdata=xlsread('stringipdata.xlsx');
GetColumnC(handles, textdata);




function itemFromColumnC = GetColumnC(handles, textdata)


itemFromColumnC = []; % Initialize to null

% Get the item number that they selected.
selected1 = get(handles.listbox1, 'value');
selected2 = get(handles.listbox2, 'value');


% Get the contents (optional - just FYI in case you want to inspect)
items1 = get(handles.listbox1, 'String');
items2 = get(handles.listbox2, 'String');
% Get the selected item (optional - just FYI in case you want to inspect)
selectedItem1 = items1{selected1};
selectedItem2 = items2{selected2};


% Now compare
if selected1 == selected2 
  % All indexes are the same so extract column C at that row.

itemFromColumnC = textdata{selected1, 3};
  disp(itemFromColumnC);

end

错误是：

？？？来自非元胞数组对象的元胞内容引用。

==> stringdata>GetColumnC 中的错误 188 itemFromColumnC = textdata{selected1, 3};

  • 单元格值是字符串
  • 我想将第三列单元格值显示为输出。

的第一个输出xlsread是一个普通（双）数组。第三个输出是一个包含 xls 的所有内容的元胞数组。你应该这样称呼它：

[t1, t2, textdata] = xlsread('stringipdata.xlsx'); % or replace t1 and t2 by ~
