Get file names and apply

ext_date = datetime(extractBetween(<your file name(here ppt_19990101_asc)>, '_', '_'), 'Format', 'yyyyMMdd');

Then read each file using textread according to your data

years = 15;

DATA = cell(years);

for yy = 1:n;

year = 1998+yy-1;

for month=1:12

if mod(year,4)==0 & (mod(year,100)~=0 & month ==2 | mod(year,400)==0) & month ==2

for Day = 1:29;

if Day<=9

P = textread(sprintf('ppt_%i020%i_asc.asc',year,year, Day),'','headerlines',6);

else

P = textread(sprintf('ppt_%i02%i_asc.asc',year,year, Day),'','headerlines',6);

end

end

elseif month==4 | month==6 | month==9 | month==11

for Day = 1:30;

if month<=9 & Day<=9

P= textread(sprintf('ppt_%i0%i0%i_asc.asc',year,year,month, Day),'','headerlines',6);

thank you "Bhaskar R" for your answer. here is a part of my long code which I wrote it. I mean this kind of calling data to recognize leap years and date.
