Reading timeseries from multiple csv files in a folder: MATLAB - matlab

Question

I have a bunch of csv files in a folder in following format, I want to extract complete time series from each (the numeric part from line #17), identify duplicate record and merge them in a ascending order according to year and date.
Specific csv file is accessible via google drive link below

Now my code is working in a following way:
SL_files = dir(sprintf('%s%s%s',fullfile(dirName),'\','*.csv'));
for idx = 1:size(SL_files,1)
disp(SL_files(idx,1).name)
fid = fopen(sprintf('%s%s%s',fullfile(dirName),'\',SL_files(idx,1).name));
data = textscan(fid, '%s %f %f %f %f %f %f', ...
'Delimiter',',', 'MultipleDelimsAsOne',1,'headerlines',16);
fclose(fid);
end
Now I could read the file. Now my problem is how to combine multiple files' data into one matrix and arrange them in a ascending order according to year and day values. Thanks!

I finally solve my problem. Here is the code:
numMat_All = [];
for idx = 1:size(SL_files,1)
disp(SL_files(idx,1).name)
fid = fopen(sprintf('%s%s%s',fullfile(dirName),'\',SL_files(idx,1).name));
data = textscan(fid, '%s %f %f %f %f %f %f', ...
'Delimiter',',', 'MultipleDelimsAsOne',1,'headerlines',16);
fclose(fid);
CharCell = data{1,1};
result = regexprep(CharCell,'[\s;:]+',' ');
numMat = cell2mat(cellfun(#str2num, result(:,1:end), 'UniformOutput', false));
numMat_All = [numMat_All;numMat];
data = []; CharCell = []; result = []; numMat = [];
end
dt = datetime([numMat_All(:,1:5), repmat(0,length(numMat_All),1)]);
T = table(dt,numMat_All(:,[6:7]));
T1 = sortrows(T,'dt');
