complex number separate the real signal about imag signal

I have a problem with the complex number

comp=a+ib

a1+ib1

a2+ib2

...

...

..

an+ibn

then I separated the real signal about the imaginary signal like this;

real(comp)

imag(comp)

the result is

a

a1

a2

.

.

an

and

b1

b2

.

.

bn

my problem how can I put the sequence the real signal after imag signal as the follow

a

a1

a2

.

.

an

b1

b2

.

.

b2n

Im not really sure what your asking but if the real part and imaginary part are stored in different arrays you can combine them using

a=real(comp);
b=imag(comp)
c=[a,b];

or look into using the cat function to concatenate them
