MATLAB: I need to remove the NaN lines from the output matrix.

celldispMATLABnanremove labelsremove nantextscan

I have a m file that is meant to read a text file and and convert the data within into a matrix. The issue is that the data has labels scattered through out and I need to remove these labels. So my code currently looks something like:
    fid = fopen('Test_Data_2.xyz', 'rt');
    datacell = textscan(fid, '%*s %f %f %f', 'HeaderLines', 2, 'CollectOutput', 1);
    fclose(fid);
    celldisp(datacell)
I then go on to use the data in the outputted matrix. The "celldisp" function currently gives me an output of;
datacell{1} =
    3.0697    1.4511    9.8552
    1.8283    2.1200    9.3934
    1.7869    3.5402    9.8658
    0.5861    4.3056    9.3636
       NaN       NaN       NaN
       NaN       NaN       NaN
    3.0705    1.4535    9.8578
    1.8297    2.1194    9.3960
    1.7861    3.5392    9.8658
    0.5880    4.3057    9.3634
Where the original data in my text file reads:

C 1.828334 2.119961 9.393412

C 1.786074 3.539174 9.865825
C 0.587989 4.305654 9.363402
Is there any way I can remove the NaN from my output matrix?

Best Answer

datacell{1}( all(isnan(datacell{1}),2) ) = [];
If you want it to change it so that rows with at least one nan (instead of all nan) are removed, change the "all" to "any"
