If your version of MATLAB is R2019a or newer, you can use readmatrix():
filename = 'DHD_10%_sec_T1.txt';
data = readmatrix(filename);
format long
data
data = 20275×3

In older versions (or just as an alternative), you can use fscanf():
filename = 'DHD_10%_sec_T1.txt';
fid = fopen(filename);
for i = 1:8 % skip 8 header lines
fgetl(fid);
end
data = reshape(fscanf(fid,'%g'),3,[]).';
fclose(fid);
format long
data
data = 20275×3
