Text line 2.........

Text line 3............

------------------

1 0.233

Text line 1..........

Text line 2.........

Text line 3............

----------------

2 0.123

3 0.234

4 0.345

Text line 1..........

Text line 2.........

Text line 3............

----------------

8 0.346

9 0.123

10 0.222

11 0.223

在 MATLAB Online 中打开

fid = fopen('abc.txt');
tline = fgetl(fid);
storedData ={};
while ischar(tline)
    if isstrprop(strtrim(tline(1)),'digit')
    disp(tline)
    storedData{end+1,1}= tline;
    end
    tline = fgetl(fid);
end
fclose(fid);
storedData
