我的实例

        f = waitbar(0,'Loading...','Name','数据读取...',...
            'CreateCancelBtn','setappdata(gcbf,''canceling'',1)');

        setappdata(f,'canceling',0);
        formatSpec = 'The current excel is: %d/%d';
        %提取excel列表数据并储存
        for i = 1:lengthXlsx
           %--------进度条------------
            if getappdata(f,'canceling')
                break
            end
            waitbar(i/lengthXlsx,f,sprintf(formatSpec,i,lengthXlsx));
           %-------------------------          
            dataList{i,1} = readExcelData([pathExcel,'\',excelList{i}]);
        end
        
        delete(f);
