I have following code:
fileID = fopen('output.txt','w');
fprintf(fileID, '%s %g ', matComp{:});
fclose(fileID);
which gives
Fe 92.44 C 3.61 Si 2.81 Mn 0.23 P 0.014 S 0.009 Ni 0.88 Mg 0.041
Now I want to change the code so I get (no number after "Fe"):
Fe C 3.61 Si 2.81 Mn 0.23 P 0.014 S 0.009 Ni 0.88 Mg 0.041
Do you know how to do it?

If you want to get rid of just the one value, how about setting it to empty inside of matComp. Note that you'll end up with one extra space...
I'll use sprintf to display what you're putting in your file:
load('matlab.mat')
sprintf('%s %g ', matComp{:})
ans = 'Fe 92.44 C 3.61 Si 2.81 Mn 0.23 P 0.014 S 0.009 Ni 0.88 Mg 0.041 '
matComp{2,1}=[];
sprintf('%s %g ', matComp{:})
ans = 'Fe C 3.61 Si 2.81 Mn 0.23 P 0.014 S 0.009 Ni 0.88 Mg 0.041 '
