a=1 2 3 4 5 6 7 8 9 b=0 1 1 2 3 2 3 2 1 resultant matrix is 1 0 2 1 3 1 4 2 5 3 6 2 7 3 8 2 9 1

a=1 2 3
  4 5 6
  7 8 9

b=0 1 1
  2 3 2
  3 2 1

How do I interleave columns?

resultant matrix is   1 0 2 1 3 1
                      4 2 5 3 6 2
                      7 3 8 2 9 1

Answer 1

[Azzi Abdelmalek]

a=[1 2 3;  4 5 6; 7 8 9]
b=[0 1 1;  2 3 2; 3 2 1]
[n,m]=size(a)
c=zeros(n,2*m)
c(:,1:2:end)=a
c(:,2:2:end)=b

Answer 2

[Jan]

a = [1 2 3;  4 5 6;  7 8 9];
b = [0 1 1;  2 3 2;  3 2 1];

c = reshape([a; b], 3, 6)
