MATLAB: Creating a Combination of Multiple Arrays

Question

I'm having trouble coming up with code to create a combination between two arrays. In my first array, result, I computed the Cartesian product between the two vectors of A.

>> A = {[1 2 3], [4 5 6]}
   c = cell(1,numel(A));
   [c{:}] = ndgrid(A{:});
   result = cell2mat(cellfun(@(v)v(:), c, 'UniformOutput', false) )
resulta =
       1     4
       2     4
       3     4
       1     5
       2     5
       3     5
       1     6
       2     6
       3     6

My second array is:

resultb =
       1     3
       2     4

I am trying to create iterations between the rows of result and result b. To make it clearer, I want my output array to look like this:

 resultc=
     1     4     1     3
     2     4     1     3
     3     4     1     3
     1     5     1     3
     2     5     1     3
     3     5     1     3
     1     6     1     3
     2     6     1     3
     3     6     1     3
     1     4     2     4
     2     4     2     4
     3     4     2     4
     1     5     2     4
     2     5     2     4
     3     5     2     4
     1     6     2     4
     2     6     2     4
     3     6     2     4

How would I create code to achieve this regardless of the sizes of matrices resulta and resultb? Thanks!

combvec(resulta', resultb')'
