Generating Daily Values using Hourly Values

i have hourly (8760h) temperature values of each year. I need to generate daily values using hourly values.

For example, i need to calculate some daily parameters like daily average temperature or daily maximum temprerature using hourly data.

Raw data is in a excel file. File format is like this;

After reading excel data, i used 'datenum' function to assign numeric value to each day. Then corrected the first day's numercal value to "1".

for i=1:8760;
raw(i,1)=datenum(Excel_data(i,1),Excel_data(i,2),Excel_data(i,3));
corrected(i,1)=datenum(Excel_data(i,1),Excel_data(i,2),Excel_data(i,3))-raw(1,1)+1;
corrected(i,2)=Excel_data(i,5);
end

Then i have,

corrected=8760x2

After this point, for example, i need calculate daily average temperature for day 1, day 2 ....day 365 at this step.

it needs to look like this;

but i couldnt manage to get a table seems like above.

T = readtable('your_xlsx_file.xlsx');
t = datetime([T{:,1:4}, zeros(size(T,1),2)]);
TT = timetable(T{:,end},'RowTimes',t) ;
TT_mean = retime(TT,'daily','mean');
TT_max = retime(TT,'daily','max');
TT_out = [TT_mean,TT_max];
