Hi there,
I have the following cell array.
f={[1;2;3;4] [5;6;7;8;9;10;11] [12;13;14;15;16;17;18;19;20;21;22;23]}
I want the output to be written to a file and it should look like....
set1
1, 2, 3, 4
set2
5, 6, 7, 8, 9
10, 11
set3
12, 13, 14, 15, 16
17, 18, 19, 20, 21
22, 23
as you can see the set number refers to the row number of cell array {f}. Also when printing the number to file, each line can have a maximum of 5 values so if you have more than 5, it continues from next line.
Thanks for your help in advance. Let me know if further clarification is needed.

Hai, try the one below....any doubts on the steps just comment on it....
f={[1;2;3;4] [5;6;7;8;9;10;11] [12;13;14;15;16;17;18;19;20;21;22;23]};
s=size(f,2);
myfile=fopen('filename.txt','w');
for i=1:3
a=cell2mat(f(i));
fprintf(myfile,'set%d\n',i);
sa=size(a,1);
for j=1:sa
fprintf(myfile,'%d ',a(j));
if mod(j,5)==0
fprintf(myfile,'\n');
end
fprintf(myfile,'\n');
end
fclose(myfile);
end

Hi
I got it to work by modifying your code as shown below. But I'm struggling to get it to write only 5 variables on a line. Also this modified code prints a comma even for the last variable as well, which is not required.
f={[1;2;3;4] [5;6;7;8;9;10;11] [12;13;14;15;16;17;18;19;20;21;22;23]};
s=size(f,2);
fileID=fopen('filename.txt','w');
for i=1:3
a=cell2mat(f(i));
fprintf(fileID,'set%d\n',i);
sa=size(a,1);
% for j=1:sa
fprintf(fileID,'%d, ',f{i});
% if mod(j,5)==0
% fprintf(fileID,'\n');
% end
fprintf(fileID,'\n');
% end
end
fclose(fileID);

here is the correct code for anyone interested.....
f={[1;2;3;4] [5;6;7;8;9;10;11] [12;13;14;15;16;17;18;19;20;21;22;23]};
s=size(f,2);
fileID=fopen('filename.txt','w');
for i=1:s
a=cell2mat(f(i));
fprintf(fileID,'set%d\n',i);
sa=size(a,1);
for j=1:sa
if (j ~= sa)
fprintf(fileID,'%d,',a(j));
else
fprintf(fileID,'%d',a(j));
end
if mod(j,5)==0
fprintf(fileID,'\n');
end
end
fprintf(fileID,'\n');
end
fclose(fileID);
