Storing results from a for loop into a cell array vector

Code so far:

C = {'TGC','TGT'};
D = {'ATA','ATC','ATT'};
k = length(C)*length(D);
V = cell(k,1);
for i=1:length(C)
  for j=1:length(D)
      V = strcat(C(i),D(j))
  end
end
Output:

V =

    'TGCATA'

V =

    'TGCATC'

V =

    'TGCATT'

V =

    'TGTATA'

V =

    'TGTATC'

V =

    'TGTATT'

I just want to store those results in a single vector V. Thanks!

Answer 1

[Andrei Bobrov]

C = {'TGC','TGT'};
D = {'ATA','ATC','ATT'};

[jj,ii] = ndgrid(1:numel(D),1:numel(C));
out = strcat(C(ii(:)),D(jj(:)));

OR

V = cell(length(C)*length(D),1);
k = 1;
for i=1:length(C)
  for j=1:length(D)
      V(k) = strcat(C(i),D(j));
      k = k + 1;
  end
end

Answer 2

[Walter Roberson]

V{j} = strcat(C(i),D(j))

It only stores the first 3 results. Is there a way to store all 6?

Answer 3

[Azzi Abdelmalek]

nc=numel(C);
nd=numel(D)
ii=repmat(1:nc,1,nd)
jj=repmat(1:nd,nc,1)
out=arrayfun(@(x,y)  [C{x} D{y}],ii',jj(:),'un',0)

Answer 4

[Jan]

...
for i=1:length(C)
  for j=1:length(D)
    V{i, j} = [C{i}, D{j}];
  end
end

Now you store all results in the cell V, but what does "in a single vector" mean?

[Azzi Abdelmalek]

He means V(:)
