Is no builtin text search routine for files; using the system grep utility or like is a very good way to do this if is just to search for a given string in file..

In Matlab, simplest is to read the full file into memory as cellstr() array and then do the string search.

txt=textread('yourfile.txt','%s','delimiter','\n');
matchstr='Home';
ix=contains(txt,matchstr);
disp(txt{ix})

You are closing the file in the loop. close the file after the loop. I assume the below should work.

function read_datapattern(filename)
fid = fopen(filename,'rt');
if fid < 0
  error('error opening file %s\n\n',filename);
end
pattern = fgets(fid);
for n = 1:32767
  nextline = fgets(fid);
  pattern = strcat(pattern, nextline);
fprintf(pattern);
fprintf('\n');
end
fclose(fid);

Mention:

    ....'CommentStyle','#')
fileID = fopen(filename);   %an example 
C = textscan(fileID,formatspec','Delimiter',',','CommentStyle','#');
fclose(fileID);
