Store data to array

I have this code for LZ78, and I want to represent the data in array form , how can I store the data as array

%Display the Token - Values can be True or False
disp_token = true;
%Display the String Covered in each Token - Values can be True or False
disp_char_string = true;
%Character _ will replace space during execution of Program. Don't use this character in the Input String
replace_space = '_';
%Path to Input File
read_file = fopen('C:\Users\JAWAHER ALMAZROEUI\Desktop\FF7.txt','r');


%Don't Change anything from now Onwards

%Look Ahead Buffer - For Remaining Characters
labuffer = fread(read_file, '*char');
%Dictionary
dict = [];

token_all= char();

for i = 1:length(labuffer)
    if(strcmpi(' ', labuffer(i)))
        labuffer(i) = strrep(labuffer(i), ' ', replace_space);
    end
end

fclose(read_file);

clearvars read_file;

i = 1;
dict_index = 1;
while i <= length(labuffer)
    compare_string = labuffer(i);
    searchresult = find(ismember(dict, compare_string));
    if(~isempty(searchresult))
        %Inner Loop to Check if Consecutive Characters Match
        continue_loop = true;
        j = 1;
        while continue_loop && ((i+j-1) < length(labuffer))
            compare_string = strcat(compare_string, labuffer(i+j));
            searchresult = find(ismember(dict, compare_string));
            if(~isempty(searchresult))
                continue_loop = true;
                j = j+1;
            else
                continue_loop = false;
            end
        end
