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

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

end

Error is:

??? Cell contents reference from a non-cell array object.

Error in ==> stringdata>GetColumnC at 188 itemFromColumnC = textdata{selected1, 3};

  • cell values are strings
  • I want to display the 3rd column cell value as the output.

の最初の出力xlsreadは通常の (double) 配列です。3 番目の出力は、xls のすべての内容を含む cell 配列です。次のように呼び出す必要があります。

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