MATLAB: Concatenate array from different main name struct

Question

I have

First.A =[  1;  2;    3];
First.B =[ 10; 20;   30];
Second.A=[ 97; 98;   99];
Second.B=[970; 980; 990];

How I can obtain (mantaining the same order of elements)?

   Result.A=[ 1;  2;  3;  97;  98;  99];
   Result.B=[10; 20; 30; 970; 980; 990];

Answer 1

Result.A=[First.A;Second.A];
Result.B=[First.B;Second.B];
