i have variable in workspace as (14*5)double. i need to convert each row to consecutive rows as (1*70)

   eg: 1 2 3
       4 5 6

output to be

MATLAB: All combinations from a set of rows without repetition of elements

Hi Timo,

It appears that for n even, the number of possible combinations of nonintersecting pairs is the product of all the odd integers less than n. The following code seems to work. The matrix B is one answer, but A = n+1-fliplr(B) puts A into a form like yours; if you run this for n=6 you can see the difference. Past n = 10 you are going to need semicolons!

For n = 18 this takes about 8 seconds on my PC and creates a matrix with 17!! x 18 = 6.2e8 elements. I went to uint8 numbers for the matrices so each of the them has as only as many bytes as elements, 620MBytes.

n = 6
B = paircombs(n)
A = n+1-fliplr(B)
function m = paircombs(n)
  if n==2
    m = uint8([1 2]);
  else
        % stack n-1 copies of previous matrix, which contains
        % values from 1 to n-2
    q = paircombs(n-2);
    qrow = size(q,1);
    m = repmat(q, n-1,1);             
        % append two new columns with values n-1, n
    onz = ones(1,size(m,1),'uint8')';
    m = [m (n-1)*onz n*onz];
        % split rows of matrix into n-1 sections, and in all but one section 
        % swap value n-1 with one of values 1..n-2
    for k = 1:n-2
      ind = k*qrow+1:(k+1)*qrow;
      msub = m(ind,:);
      msub(msub==(n-(k+1))) = n-1;
      msub(:,end-1) = n-(k+1);
      m(ind,:) = msub;
    end
  end
end

MATLAB: How to save each loop data in consecutive rows

 b = zeros(3,2*3);
 for k = 1:3
   a = rand(3,2);
   b(k,:) = reshape(a.',1,[]);
 end

Note: Your output is 3 by 6, not 3 by 5.
