我不会t write very well English, sorry if you can非常了解我。
我做了我的gui，一切都很好。但是，当我插入数字来计算结果。出现错误：错误
matlab.graphics.internal.figfile.FigFile /读取＆GT; @（hObject，EVENTDATA）GUIDEHARDYCROSS（＆＃39; CALCULAR_Callback＆＃39;，hObject，EVENTDATA，guidata（hObject））
评估UIControl回调时出错。
这是我的代码。
function CALCULAR_Callback(hObject, eventdata, handles)
