Dear all, I have a code that looks like that
for i=1:10
mystruct.filename=sprintf('test %d',i);
mystruct.number=1;
end
and I want to dump these data in ascii file with comma or tab delimited Every line in the file I want to be one iteration so the file to look like
test1,1 test2,2 test3,3 ...
How can I dump a struct to an ascii file?
Best Regards Alex

Are you sure that your code looks like this? Since the above code will result in one struct with
filename: 'test 10'
number: 1
as values/fields.

Hi,
only a guess:
for i=1:10
mystruct(i).filename=sprintf('test %d',i);
mystruct(i).number=i;
end
txt = struct2cell(arrayfun(@(x) structfun(@num2str,x,'UniformOutput',false),mystruct));
tmp = squeeze(strcat(txt(1,1,:),',',txt(2,1,:),';'));
fid = fopen('out.txt','w');
fprintf(fid,'%s',strcat(tmp{:}))
fclose(fid)

Another guess. I created a dummy cell a which has some rows and columns:
a = {'abcde', 'fghi', 'jk','l'; '1','2','3','4'};
[n m] = size(a);
b = cell(n,2*m);
b(:,1:2:2*m-1) = a;
b(:,2:2:end) = {','};
b(:,end) = {';'};
fid = fopen('out.txt','w');
for i=1:n
fprintf(fid,'%s \n',strcat(b{i,:}));
end
fclose(fid);
