Hi everyone!

I have a problem like this:

a = [1 2 3]

b = [1 2 3]

and I want matrix combine 2 matrix a and b.

Cuppose,It is matrix C and size of C is 9x2 matrix

C = [ 1 1; 1 2; 1 3

2 1; 2 2; 2 3;

3 1;3 2; 3 3]

Does Matlab have any function like this?

combvec() from the Deep learning toolbox is most easiest solution

a = [1 2 3]
b = [1 2 3]
C = combvec(a, b).'; % if the order of column is important: C = fliplr(combvec(a, b).');

The other solution is to use ndgrid()

a = [1 2 3]
b = [1 2 3]
[A, B] = ndgrid(a, b);
C = [B(:) A(:)]
