I need create a function for order pairs

Hi I nedd create a function for do something like this (using for loops)

A = [1,2,3];

B = [4,5,6];

LA = length(A);

LB = length(B);

LT = LA*LB;

% The matrix of pair orders always be (n,2), in this case C(LT,2) = C(9,2)

C = zeros(LT,2);

C = [(1,4) ; (1,5) ; (1,6) ; (2,4) ; (2,5) ; (2,6) ; (3,4) ; (3,5) ; (3,6)];

I try using this kind of code:

C = []:

for i =1:LT

C(i) = B(A);

% or

C(i) = B[];

end

Any idea?

You can create indices with meshgrid or ndgrid, no loop needed.

[indA,indB]=ndgrid(1:numel(A),1:numel(B));
C=[A(indA(:)).' ; B(indB(:)).'];
