divide different data in parts and put it in one after another

I have data A=4000 length, b=4000 length. I want to divide A in 4 parts with each part 1000 and same thing with B. then I want to put divided data of A and B one after another so to make single row i.e. C=[ 1000(A) 1000(B) 1000(A) 1000(B) 1000(A) 1000(B) 1000(A) 1000(B)]. how to do it

Answer 1

[KSSV]

A1 = reshape(A,1000,4);
  B1 = reshape(B,1000,4);
  iwant = zeros(1000,8);
  iwant(:,1:2:end)=A1;
  iwant(:,2:2:end)=B1;

but it becomes 10*8 matrix. I want data in single row. how to do it.

@Ram: Really a 10x8 matrix? You mean 1000x8, don't you? Simply append:

iwant = iwant(:).'

[Jay Hanuman]

yes I run for 40 instead 4000 so it becomes 10*8.

iwant = iwant(:).'

works
