This works:
aa = [a'; a'];
aa = aa(:)
aa =
111.23
111.23
354.45
354.45
186.69
186.69

354.4481
354.4481
111.2320
111.2320

@Abdulbaki Atakan: Then you use another code. Try it again:
a = [111.23199; 354.44814; 186.69329]
aa = [a'; a'];
aa = aa(:)
This replies exactly what you have been asking for.

Another way, using the reshape function:
aa = reshape([a(:) a(:)]', [], 1)
aa =
111.23
111.23
354.45
354.45
186.69
186.69

With a modern Matlab version:
aa = repelem(a, 2, 1)
