Question

How could I construct automatically a dataset like the one below, assuming that the number of columns of matrix summary_whts is approx. 400???

lrwghts = dataset(...
         {summary_whts(:,01),'w00'},...
         {summary_whts(:,02),'w01'},...
         {summary_whts(:,03),'w02'},...
         {summary_whts(:,04),'w03'},...
         {summary_whts(:,05),'w04'},...
         {summary_whts(:,06),'w05'},...
         {summary_whts(:,07),'w06'},...
         {summary_whts(:,08),'w07'},...
         {summary_whts(:,09),'w08'},...
         {summary_whts(:,10),'w09'},...
         {summary_whts(:,11),'w10'},...
         {summary_whts(:,12),'w11'},...
         'ObsNames',summary_mthd);

Answer 1

At last, I found it! This is what I was looking for:

cat = [];
for i = 0:(size(X,2)),
    cat = [cat;sprintf('w%03d',i)];
end
cat = cellstr(cat);
lrwghts = dataset({summary_whts,cat{:}},'ObsNames',cellstr(summary_mthd));
