MATLAB: How do i combine two different sized vectors

data importvectors

 A = [1;3;5;7;9;11] and B = [2;4;6;8;10;12;14;16] 
to make  C = [1;2;3;4;5;6;7;8;9;10;11;12;14;16]

C=sort([A;B])

I suggest going over the getting started documentation and taking a look at this

x = 1:5;
y = 1:5;
t = -1:1/2:1;
u = 0:1/2:2;
y = repmat(y,5,[]);
t = repmat(t,5,[]);
z = y-(t+u'*x);
z = z(:)'

X = [1;1;1;2;2;3;3;3];
B = [5;6;7;4;1;2;2;3];
A = accumarray(X,B,[],@min);
Y = any(bsxfun(@eq,A,B.'));
C = zeros(size(B));
C(Y) = B(Y)

where the output is
