In a simular vein to a previous query.
Could somone kindly show me how to finnish off what appears to be another simple formatting problem. Nearly there, but the last step has beaten me again!
I basically need the transpose of 'ofmf.txt'. The script to produce this is 'script.m'.
Tried with 'scriptT.m', but it outputs 'ofmtT.txt'. Just a question of somehow appending the 'fracs' data to the names.

It is not just a trivial transpose. Here are some approaches:
  1. use a loop and indexing,
  2. use a table (recommended),
  3. use e.g. COMPOSE and display the text,
  4. convert the numeric data into a cell array, concatenate with the header, then one FPRINTF call with a comma-separated list.
Unfortunately this forum implicitly adds newlines after each FPRINTF call, so I gave up trying to give examples.

Not exactly -- it adds newlines at the end of each code line that does an fprintf. It also removes empty lines created by fprintf
fprintf('A'); fprintf('B')
AB
fprintf('C')
C
fprintf('\n\n\n\n')
fprintf('D')
D
disp(string(newline)+newline+newline+newline)
fprintf('E')
E
It is a nuisance sometimes.

If you want the transpose in the sense of having a row labeld Mix Ratio, and a row labeld '*H' and so on, then you have no hope of proceeding by way of printing all of the row names at one time and then going back and filling in the values.
If that is what you are after, I suggest you consider
T = array2table(fracs, 'VariableNames', pnames);
TT = rows2vars(T);
writetable(TT, 'ofmfT.txt', 'Delimiter', '\t', 'WriteVariableNames', false)

I accepted your answer. Fabio's also worked with a little tweak.
I was just interested in a finnishing touch to Walter's slightly different approach.

I like Walter's approach too (that's why I voted for his answer).

Ran in:
Yes, a for loop is likely the simplest and clearest approach.
Without a loop is possible, but ... ugh, that cell array:
H = {'hello','world'};
M = randi(9,3,2);
Horizontal:
F = [repmat('%9d',1,2),'\n'];
fprintf('%9s',H{:})
hello world
fprintf('\n')
fprintf(F,M)
3 1 2 9 7 9
Vertical:
F = ['%9s',repmat('%9d',1,3),'\n'];
C = [H;num2cell(M)]; % ugh
fprintf(F,C{:})
hello 3 1 2 world 9 7 9
