I need MATLAB to load a file but the file is not a uniform matrix of number. I am using the function in matlab: load('file_name.txt'); So for example the file opens as:
46
Graphene-Cs
C 3.069663 1.451149 9.855179
C 1.828334 2.119961 9.393412
C 1.786922 3.540219 9.865837
C 0.586064 4.305576 9.363573
C 0.589753 5.714887 9.934629
C 3.115297 0.068234 9.349019
C 5.495670 1.480486 9.955026
C 4.286234 2.221273 9.447150
C 4.255019 3.612844 9.937289
C 3.019751 4.340426 9.478676
C 3.007670 5.775853 9.955533
But I need it to load the following into matlab:
3.069663 1.451149 9.855179
1.828334 2.119961 9.393412
1.786922 3.540219 9.865837
0.586064 4.305576 9.363570
0.589753 5.714887 9.934629
3.115297 0.068234 9.349019
5.495670 1.480486 9.955026
4.286234 2.221273 9.447150
4.255019 3.612844 9.937289
I am thus receiving the error:
Error using load Number of columns on line 3 of ASCII file C:\Documents\file_name.txt must be the same as previous lines.
Error in get_diff (line 9) load('file_name.txt');
Can anyone help me with this?

fid = fopen('file_name.txt', 'rt');
datacell = textscan(fid, '%*s%g%g%g', 'HeaderLines', 2, 'Collect', 1);
fclose(fid);
YourData = datacell{1};

Use fgetl() and read just however many lines you want to.
