fprintf formatting problem with cell and array matrix 2

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.

Just a question of somehow appending the 'fracs' 22x10 matrix data (below last cell name H2O(S) one column right and up to first cell name *H.

[Stephen23]

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.

[Walter Roberson]

Unfortunately this forum implicitly adds newlines after each FPRINTF call

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.

Sorry for delay in accepting your answer. Yes it works perfectly. Much apperciated :)

[Voss]

You're welcome!

Answer 2

[Walter Roberson]

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)

[Star Strider]

Brantosaurus is using R2017a. I don’t believe Brantosaurus can use ‘pnames’ as variable names in a table, since most of them aren’t valid MATLAB variable names. That ability arrived a couple releases later. if I remember correctly

[Walter Roberson]

Oh, good point about the version -- I didn't pay attention to that. rows2vars() was not introduced until R2018a, which IIRC was also the release that started supporting other variable names for tables.

[Star Strider]

My first thought initially was to use table until I checked that. The ‘pnames’ array won’t work as variable names.

[Walter Roberson]

Should still be able to do

T = [table(pnames(:), 'VariableNames', 'ID'), array2table(fracs.')];
writetable(T, 'ofmfT.txt', 'Delimiter', '\t', 'WriteVariableNames', false)

I just went back to R2016a to confirm (didn't have R2017a handy): Delimiter and WriteVariableNames were supported back then.

[Star Strider]

I didn’t check all the details. Avoiding writing the variable names would solve that problem.

[Brantosaurus]

Hi Walter. Tried your R2017a suggestion, but got the following (see attached).

Is there an easy workaround?

[Walter Roberson]

T = [table(pnames(:), 'VariableNames', {'ID'}), array2table(fracs.')];

[Brantosaurus]

It worked! That looks neat. No fiddly formatting.

How might i get the 'mix ratio' title followed by the of array as the first line preceeding the table. Similar to below.

      Mix ratio  5.0000000e-01   1.0000000e+00   1.5000000e+00   2.0000000e+00   2.5000000e+00   3.0000000e+00   3.5000000e+00   4.0000000e+00   4.5000000e+00   5.0000000e+00   5.5000000e+00   6.0000000e+00   6.5000000e+00   7.0000000e+00   7.5000000e+00   8.0000000e+00   8.5000000e+00   9.0000000e+00   9.5000000e+00   1.0000000e+01   1.0500000e+01   1.1000000e+01

[Walter Roberson]

part1 = table([{'Mix ratio'}; pnames(:)], 'VariableNames', {'ID'});
part2 = array2table([of; fracs.']);
T = [part1, part2];

[Brantosaurus]

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.

[Voss]

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

With mixed data tipes the simplest thing is to use a for loop

clear, clc, close all
%% input data

fracs = ...

[Stephen23]

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
