There are 500 such values. I wanted to split this file based on the delimiter # into 500 different files named file1.txt, file2.txt and so on.
Can someone please help me with this.

wholecontent = fileread('c:\pathtofile\filename.txt');
splitcontent = strsplit(wholecontent, '#');  %split content at each #
for fidx = 1:numel(splitcontent)  %iterate over each section
   fid = fopen(sprintf('c:\pathtodestination\file%03d.txt', fidx))
   fwrite(fid, splitcontent{fidx});   %and save
   fclose(fid);
end
Or something like that.
