How can I append multiple elements to the end of a vector?

When creating a random vector how can I create a new vector with all of the same elements of the first vector, but with the elements greater than or equal to a certain number appended to the end?

For example

>> A=randi([0 10],1,20)

And then the new vector would have the same elements as A except all of the elements >=6 would be appended to the end of the vector.

B=[A(A<6), A(A>=6)]

or

ind=(A>=6);
B=[A(~ind), A(ind)]

or if you want to keep the original elements of A and just add the elements that hold your condition:

B=[A, A(A>=6)]

this is based on logical indexing, see http://www.mathworks.nl/company/newsletters/articles/matrix-indexing-in-matlab.html
