Hi -
I'm trying to write a cell array containing something like (to a file):
'A1' 'A2' 'A3'
[2291x1 double] [1424x1 double] [1545x1 double]
Is there any quick and easy way to do so?
I appreciate any suggestion.
Thank you
Pearl

%for mor columns (676) you can use this:
T={'A1' ,'A2' , 'A3';rand(2291,1) rand(1424,1) rand(1545,1)}
s='ABCDEFGHIJKLMNOPQRSTUVWXYZ';c=s';
for k=1:length(s)
for l=1:length(s)
c=char(c,[s(k) s(l)])
end
end
for k=1:size(T,2)
n=length(T{2,k})+1;ch1=strtrim(c(k,:))
xlswrite('ans_xls126.xlsx',T(1,k),sprintf([ ch1 '%d:' ch1 '%d'],1,1))
xlswrite('ans_xls126.xlsx',T{2,k},sprintf([ ch1 '%d:' ch1 '%d'],2,n))
end

MATLAB is a bit weak on routines to write cell arrays all at one time. But you can use something like this:
headers = YourCell(1,:);
header_format = '%.15s %.15s %.15s\n';
values = cell2mat(YourCell(2,:));
numcols = size(values,2);
value_format = [ repmat('%.15g ', 1, numcols-1), '%.15g\n');
fout = fopen('YourFile.txt', 'wt');
fprintf(fout, header_format, headers{:});
fprintf(fout, value_format, values.'); %transpose is important!
fclose(fout);

NaN will be written to the file if you use the structure such as I showed.
In order to write in "columns", you need to define how you can tell columns apart, such as how you can tell whether there are one blank columns or two blank columns instead. When that is defined we can help write the code.
