I need a matrix which numbers ascend in the following way:
If I have the columns:
x=[1 2 3]
y=[4 5 6]
I want the matrix to be like:
A=[1 4
1 5
1 6
2 4
2 5
2 6
3 4
3 5
3 6]
I hope someone can help me with this.

x=[1 2 3]
y=[4 5 6]
x1=repmat(x,numel(y),1)
out=[x1(:) repmat(y',numel(x),1)]

I got it myself. Thank you for the answer. I used this code:
x1=repmat(i,numel(j),1);
x1=sortrows(x1);
out=[x1(:) repmat(j,numel(i),1)]

I meant to say 1 in stead of 001. But I allready got the solution I wanted. Thanks

x = repmat(x,numel(y),1)
y = repmat(y,1,size(x,2))
A = [x(:) y(:)]

[ii,jj] = ndgrid(y,x);
out = [jj(:), ii(:)];
