How should i write the AVG and standard deviation data into .txt file?
d = 'E:\\ \\ DummyFile\\';
filePattern = fullfile(d, 'Run*');
file = dir(filePattern)
n = length(file)
for k = 1:n
baseFileName = file(k).name;
FullFileName = fullfile(d, baseFileName, 'dummy.csv');
temp = readtable(FullFileName, 'ReadVariableNames' true, 'ReadRowsNames' true);
x(:, :, k) = temp(:, :);
end
%Finding Average and Std
Avg = mean(x,3);
Standard_deviation = std(x,0,3)

% Ask for the name of the file that the user wants to save.
startingFolder = pwd % or wherever you want.
defaultFileName = fullfile(startingFolder, '*.*');
[baseFileName, folder] = uiputfile(defaultFileName, 'Specify a file');
if baseFileName == 0
% User clicked the Cancel button.
return;
end
fullFileName = fullfile(folder, baseFileName)
% Open file for writing.
fid = fopen(fullFileName, 'wt');
if fid ~= -1
% Was able to open it successfully, now write stuff into it.
fprintf(fid, 'Average = %f.\nStandard Deviation = %f.\n', Avg, Standard_deviation);
fclose(fid);
else
errorMessage = sprintf('Error opening %s for output.', fullFileName);
uiwait(errordlg(errorMessage));
end

Simply change the filename before each call to writetable().
fullFileName = 'AvgT.csv';
writetable(AvgT, fullFileName, 'Delimiter', ',', 'WriteRowNames', true);
fullFileName = 'StdT.csv';
writetable(StdT, fullFileName, 'Delimiter', ',', 'WriteRowNames', true);
fullFileName = 'SlopeT.csv';
writetable(SlopeT, fullFileName, 'Delimiter', ',', 'WriteRowNames', true);
