Hi.
I'm making the matrix with sortrows.
Here is what I want to make it.
20 20 20
20 20 21
20 20 22
20 20 23
20 20 24
20 20 25
20 21 20
20 21 21
20 21 22
20 21 23
20 21 24
20 21 25
20 22 20.....
To do this I tried with this code:
A=[20 21 22 23 24 25];
B=[20 21 22 23 24 25];
C=[20 21 22 23 24 25];
sets = {A, B, C};
[x y z] = ndgrid(sets{:});
cartProd = [x(:) y(:) z(:)];
sorted_cartProd = sortrows(cartProd, 1);
sorted_cartProd
Then I got this.
sorted_cartProd =
20 20 20
20 21 20
20 22 20
20 23 20
20 24 20
20 25 20
20 20 21
20 21 21
20 22 21
20 23 21
20 24 21
20 25 21
20 20 22
20 21 22 ...
What I expect is start from third column but it starts to change from sedone column.
In this case, what should I do?
