%% Here data for x sxcale reeat from 0 to 0.0427 six times, when I plot, then a line I laos found form 0.0427 to 0.0000, and five lines I found in %%plot, I do not want to plot between these points or I don;t want these five lines, I wants to break curve after 0.427. Along with this, I also %%want to add horizontal line at 0.0128 and 0.0342 on x-axis and vertical line at 453.7071 on y-axis.

For that data file, 0.0000 repeats every 11, not every 401. The entire file only has 66 data lines.
The following code tries to automatically detect the length before repetition.
filename = 'https://www.mathworks.com/matlabcentral/answers/uploaded_files/1079015/CO-ph-d.txt';
data = readmatrix(filename);
col1 = data(:,1);
repeatlength = find(col1(2:end) == col1(1), 1);
x = reshape(data(:,1), repeatlength, []);
y = reshape(data(:,2), repeatlength, []);
x(end+1,:) = nan;
y(end+1,:) = nan;
plot(x(:), y(:));
