Best Answer

I don't really know what is asked, categorize doesn't mean much. If it's help to read the file into a table, then as said readtable is your friend. For your example file,
data = readtable('yourfilename', 'Delimiter', {' ', '; '}, 'HeaderLines', 5)
will read the file more or less correctly. You can then tidy up the table with for example:
data([1 2], :) = [];  %to remove the two empty rows after the header
data = [table(datetime(data.Date_yyyy_MM_dd_, 'InputFormat', 'yyyy/MM/dd') + duration(data.Time_hh_mm_ss_), 'VariableNames', {'DateTime'}), data(:, 3:end)]  %to replace column 1 and 2 by a single datetime column
