Ok, so how do you place elements of one array into another array, so that they are included in either the beginning of the array or the end of the array?

There are many ways to join elements of two arrays. For example, let’s say you have two 2-by-2 matrices A and B:
A = [1 2; 3 4];
B = [5 6; 7 8];
Then the following commands concatenate B to the end of A horizontally:
H1 = [A B]
H2 = horzcat(A,B)
H3 = cat(2,A,B)
The first argument in the cat function (2) tells it to add B as additional columns of A.
These commands concatenate B to the end of A vertically:
V1 = [A; B]
V2 = vertcat(A,B)
V3 = cat(1,A,B)
The 1 tells cat to add B as additional rows of A.
For additional concatenation examples, see:

just using c = [a , b]
ex: a = [1 2 3] b = [4 5 6] c = [a,b]
--> c = [1 2 3 4 5 6]
