How to edit a text file using matlab?

Hello,

I have a text file that is in the following form:

    1 1 4 0 6
    1 2 9 5 6

I want to add braces and semicolons on all lines of the file to have the following form:

    {1,1,4,0,6},
    {1,2,9,5,6}

I am looking for a matlab function that does this automatically without having to change my file manually because the original file contains 200 lines. thank you

fid =fopen('your_file.txt');
C=textscan(fid,'%s','delimiter','\n');
fclose(fid);
for k=1:numel(C{1,1})
    tmp = regexp(C{1,1}(k),'\s'); % find empty spaces
    C{1,1}{k,1}(tmp{1,1}) = ','; % substitute empty spaces by ','
    C{1,1}(k) = strcat('{',C{1,1}(k),'},'); % add brackets
end
% print new file
fName = 'new_file.txt';
fid = fopen(fName,'w');            % Open the file
for k=1:numel(C{1,1}) 
  fprintf(fid,'%s\r\n',C{1,1}{k,1}); 
end
fclose(fid);

IGNORE this comment I just want to have a way to save this in my account as I like the code.

Here is an another way to do that without using for-loop.

% After textscan
C = {'1 1 4 0 6';'1 2 9 5 6'};

% Replace space with ','
C = regexprep(C,'\s',',');

% Add '{' and '},' for each line
C = cellfun(@(x) ['{',x,'},'],C,'UniformOutput',false);

% Delete the last ',' at the last line
C(end) = regexprep(C(end),',$','');
