在 MATLAB Online 中打开

DHD_10%_sec_T1.txt

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
  -0.000050862627887  -0.124530710279942   0.008000000379980

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
