I have two matrices and i want to concatinate the 1st element of fist matrix with the first element of second matrix and so on (i'th with i'th)

Below are the arbitrary matrices (can be bigger but with same dimensions)

a=[1 2 3 4 5 6];
b=[10 11 12 13 14 15];

How can i get the result matrix?

result=[1 10 2 11 3 12 4 13 5 14 6 15];

"Below are the arbitrary matrices (can be bigger but with same dimensions)"

result=reshape([a(:) b(:)].',1,[])

Or slightly easier:

reshape([a; b], 1, [])

Alternative:

a = [1 2 3 4 5 6];
b = [10 11 12 13 14 15];
c          = zeros(1, numel(a) + numel(b));
c(1:2:end) = a;
c(2:2:end) = b;

@ARN: I answer a question, if I find the time to do this and if I have some potentially useful ideas about the question. It is considered to be impolite to push others to answer questions. Imagine how much noise you would find in the forum, if anybody advertises his or her questions in the section for comments of other threads. So please don't do this.
