matFiles = dir('*.mat') ; 
matFiles_name = {matFiles.name} ; 
idx = find(~cellfun(@isempty,strfind(matFiles_name,'2015'))) ;
matFiles_name(idx)

[Mohammed Yousuf]

But it is not loading any mat file and idx=[]; (empty)

I want to load the file which contains that particular year

[KSSV]

MatFiles_name got the names of mat files?

[Mohammed Yousuf]

Yes, but i want to load only the files which consist of the year which i want,

viz. If I wnat only 2005 files

then I should load only latest_res_log102005_alt.mat ; latest_res_log102005_lat.mat; latest_res_log102005_long.

Then instead of 2015 give log102005. Change the string to your requirement.
