MATLAB Central Newsreader - Printing a cell array

Printing a cell array

n o s p a m p l e a s e — Fri, 09 May 2008 06:16:03 -0400

I have a cell array as follows:

Names = {'Jon' ; 'Hur' ; 'Osl' ; 'Got'};

I want to print them such one element goes in a line as follows:

1 Jon
2 Hur
3 Osl
4 Got

I wrote the following code:
nb = 4;
fid = fopen('myoutput.txt','w');
fprintf(fid, '\n %d %s', [1:nb], Names{:});
fclose(fid);

but it is not working out properly.

Any suggestions.

Does this help?

for k=1:nb
fprintf('%d %s\n',k,Names{k})
end

Cheers
Bob

Yes it works but I want it in vector form i.e. something as follows:

fprintf('%d %s\n',[1:nb],Names{[1:nb]})

and the above doesn't work. Any guess how I can put it in vector form.

An example of comma-separated list expansion:

x = 1:3 ;
t = {'AA','B','CCC'} ;

% one big cell array
M = [num2cell(x) ; t]

% expansion
fprintf('\n%d\t %s',M{:})

Note that the order of M is important, before you apply
comma-separated list expansion. You might have to transpose
M before.

There is one more crude way.
Try this if it works :

fid = fopen('myoutput.txt','w');
index = { '1 ' ; '2 ' ; '3 '; '4 '};
Names = {'Jon' ; 'Hur' ; 'Osl' ; 'Got'};
Names2=(strcat(index',Names'))';
fprintf(fid, '\n %s',Names2{:});
fclose(fid);
