Hi given the following arrays

A = [1 1 1 1 4 4 4 4 6 6 6 6 6 6]
B = [2 2 2 2 2 2 2 2 2 2 7 7 7 7 7 7 7 7 8 8 8 8 9 9 9 9]

I want to create a new vector C that is the intersection of A and B

C = [1 2 1 2 1 2 1 2 4 2 4 2 4 2 4 2 6 2 6 2 6 7 6 7 6 7 6 7 7 7 7 7 8 8 8 8 9 9 9 9 ]

So C is created by insert one value of B after one value of A, till the end.

在 MATLAB Online 中打开

>> A = [1 1 1 1 4 4 4 4 6 6 6 6 6 6];
>> B = [2 2 2 2 2 2 2 2 2 2 7 7 7 7 7 7 7 7 8 8 8 8 9 9 9 9];
>> N = min(numel(A),numel(B));
>> C = [reshape([A(1:N);B(1:N)],1,2*N),A(N+1:end),B(N+1:end)]
C =
   1   2   1   2   1   2   1   2   4   2   4   2   4   2   4   2   6   2   6   2   6   7   6   7   6   7   6   7   7   7   7   7   8   8   8   8   9   9   9   9
