Does this solution work for you? I have not tested it, let me know if it works.
files = dir('*.h5'); % Find the files with extension .h5 in the current directory.
monthsStr = {'01';'02';'03';'04';'05';'06';'07';'08';'09';'10';'11';'12'};
for ii = 1:numel(files) % In theory, you have 365 files.
for year = 2009:2010
for jj 1:numel(monthsStr)
nameFound = strfind(files(ii).name, ['GSAT' num2str(year) monthsStr{jj}]); % The mistake was here =P .
if nameFound
fid = fopen(files(ii).name);
% Do whatever you need with the files here.
fclose(fid);
end
end
end
end

Thank you answer
my codes are as follows
path=('/Net/Groups/BSY/people/upimple/temp/gosat/');
files=dir('*h5');
monthsStr={'01';'02';'03';'04';'05';'06';'07';'08';'09';'10';'11';'12'};
for ii=1:numel(files)
for year=2009:2010
for jj=1:numel(monthsStr)
nameFound=strfind(files(ii).name,['GOSATTFTS' num2str(year) monthsStr(jj)]);
if nameFound
laitude=hdf5read(strcat(path,files(ii).name),'/Data/geolocation/latitude');
longitude=double(hdf5read(strcat(path,files(ii).name),'/Data/geolocation/longitude'));
xco2=double(hdf5read(strcat(path,files(ii).name),'/Data/mixingRatio/XCO2'));
end
end
end
end
and I got error
??? Error using ==> cell.strfind at 35
If any of the input arguments are cell arrays, the first must be
a cell array of strings and the second must be a character array.
Error in ==> temp at 16
nameFound=strfind(files(ii).name,['GOSATTFTS'
num2str(year) monthsStr(jj)]);
My mistake, you must use "{" and "}" instead of "(" and ")". I edited the answer, take a look at it ;).

Surely the filenames contain some coded tags with which you could identify which files go with which month?
Have a look here.

my problem is that I wanted to read only specific files from all files e.g for whole year I have 365 files , I want to read them separately / month ( So accordingly every month contains 31,30 28or 29 files). the files names give me the year and month and day (gmat20090211_1245Stv.h5).
