Hi,
i'm using this command to create a .txt of data. The data are placed in the first row. Is there a way to add fix labels in the first row and put the data in the second row? Thanks a lot for any help.
dlmwrite('c:\data.txt', y, 'delimiter', '\t');

you could just add a simple fopen command prior to your dlmwrite command:
fid = fopen('c:\data.txt','w');
fprintf(fid,'H2 CO CO2 Ar');
fclose(fid)
dlmwrite('c:\data.txt',y,'-append','delimiter','\t');

Hi Thanks for the answer, but in that case I have the "Your text Here" always in the cell attached to the data:
This is what I got from Matlab: 1 5 15 3
And I would like to have something like that. The first row shall be always the same.
H2 CO CO2 Ar
1 5 15 3

The intent was for you to replace 'Your Text Here' with the line that you're wanting. In this case my understanding is that you would want fprintf(fid,'H2 CO CO2 Ar');
I've adjusted my answer accordingly.
