Hello I want to combine two column vector matrices into one column vector matrix like the example
A=[1;4;6;7;8]
B=[10;21;11;9]
C must be like:
C=[1;10;4;21;6;11;7;9;8]
I need a general answer because I have many and large columns. Thank you

nA = length(A);
nB = length(B);
C = zeros(nA + nB, 1);
nCommon = min(nA, nB);
C(1:2:nCommon*2-1) = A(1:nCommon);
C(2:2:nCommon*2) = B(1:nCommon);
if nA < nB
C(nCommon*2+1:end) = B(nCommon+1:end);
elseif nA > nB
C(nCommon*2+1:end) = A(nCommon+1:end);
%if the lengths were the same then everything was copied by the common processing
end

In the example you gave do this:
C = zeros(9,1);
C(1:2:end) = A;
C(2:2:end) = B;
For a general answer you need to define the generality you are seeking. Give us more information. For example, if the numbers in two vectors differs by more than one element, what do you wish as a result?
