How can i leave the vector result?

I have a problem I need a result dB(2)=7 but that result coming. What will i do?

A(1)=4;
A(2)=5;
A(3)=6;

 row=2; %row is variable. It is given one.
dB(row)=A(row)+2
dB =

     0     7

I need result with brackets like that dB(1), dB(2), dB(3). But it is changed to vector.

Is there another way?

Thanks!

If you need dB(2)=7 write

dB(2)=7

If not provide more information

What are you expecting as result?

[Light]

All result is changed dB= ........

My expected result must have brackets dB(n)=......

[Azzi Abdelmalek]

What you are asking for is how to display B(n)=

row=2  
dB(row)=A(row)+2;
[sprintf('dB(%d)=',row) num2str(dB(row))]

Have you tried the above code? and what do you mean: use it next calculation? can you explain?
