I would like to ask for your advice. I have a Data.xlsx file. I would need to create a new "Table".
I'm just sending an example. The table "T15all" contains 2977 rows. New "Table" must have data from T15all in the first column. Next are the other columns (I assume "numel") from Data. The groups in the new "Table" will be created according to the variable "Data.ID15all".
I uploaded a new excel ("Result") where the results are processed in excel. I would need to import this procedure into Matlab. It will be a combination of "countif" and "vlookup".
Could you please help me?
I managed to use the "grpstat" command. I understand the error but I can't solve it.
well thank you

(1) Import the data into MATLAB:
D = readmatrix('Data.xlsx');
(2) Convert to date time:
DTime = datetime(D(:,1), D(:,2), D(:,3), D(:,4), D(:,5), D(:,6), D(:,7));
(3) Convert to table:
Data = table(DTime);
Data = renamevars(Data, 'DTime', 'ID15all');
