How do i mix two different size arrays i.e A=[a1 a2 a3...a12] and B=[b1 b2 b3...b9] so that the resulting one is C={a1 b1 a2 b2 a3 b3...] and the longer vector is the ones whos values continue when the shorter one is exhausted of values. I also need to do this using horizontal concatenation, horzcat, reshape, lengths, zeros and ones matricies and other commands.

A = rand(1,3)
B = rand(1,7)
N = min(numel(A),numel(B));
C = [reshape([A(1:N);B(1:N)],1,[]),A(N+1:end),B(N+1:end)]

"I want to be able to understand the different parts of the code."
It is often useful to "break" down code when debugging or trying to understand code:
A = rand(1,3) % fake data (row vector)
B = rand(1,7) % fake data (row vector)
N = min(numel(A),numel(B)) % N = shortest vector length
M = [A(1:N);B(1:N)] % 2xN matrix
R = reshape(M,1,[]) % 1x(2*N) vector... but note the order!
X = A(N+1:end) % remaining elements
Y = B(N+1:end) % remaining elements
C = [R,X,Y] % join them all together
