This is exactly what Matlab's editor does already. Why do you want to re-create such a standard tool?

But if you really want to do this, what does "show it on screen under respective heading" mean? A uitabgroup? While it is not very complicated to create such a tab group and add some buttons for loading and saving, this is a tedious work. Try to start writing a solution and ask a specific question.

MATLAB: Edit entries in textfile with fopen

Hi,

One way to to do this.

Read the whole contents of your file in one cell.

Modify the line you want (be careful to keep the syntax).

rewrite the textfile with the new cell.

% read the data
fid = fopen('Myfile.txt','r');
MyText = textscan(fid,'%s','delimiter','\n');
fclose(fid);
%reconcatenate in a cell
MyText = [MyText{:}];
% Modify the content : here, the 12th line, new string.
MyText{12} = '2.3';
% rewrite the file
fid = fopen('Myfile.txt','wt');
fprintf(fid,'%s\n',MyText{:});
fclose(fid);

You can't really just specify a line to modify.

Skip the writetable.

filename = 'goal.txt';
[fid, msg] = fopen(filename, 'wt');
if fid < 0
    error('Failed to open output file "%s" because "%s"', filename, msg);
end
fprintf(fid, '"Time"   "X"   "Y"   "Pressure"\n');
fprintf(fid, '%g   %g   %g   %g\n', YourTable{:,:}.' );   %transpose is needed
fclose(fid);
