Creating a matrix help

a=[111.23199; 354.44814; 186.69329]

b=[111.23199;111.23199;354.44814;354.44814;186.69329;186.69329]

How can I create a matrix "a" in the form of a matrix "b"?

This works:

aa = [a'; a'];
aa = aa(:)

aa =
       111.23
       111.23
       354.45
       354.45
       186.69
       186.69

aa =

186.6933
186.6933
354.4481
354.4481
111.2320
111.2320
186.6933
186.6933
354.4481
354.4481
111.2320
111.2320

It happens like this

@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)
