CASE 1 :
A = [540]
B = [0,15]
How to insert B(1) as A(1) and B(2) as A(3) ===>>> OUTPUT SHOULD BE LIKE: A = [0,540,15]
Case 2 :
A = [0,540]
B = 15
How to insert B(1) as A(3) ===>>> OUTPUT SHOULD BE LIKE: A = [0,540,15]

These are very basic concepts in MATLAB vector creation and its indexing. You can go through these links to know how to do these things.
For example in the first case,
A = [540];
B = [0,15];
A = [B(1) A B(2)]
A =
0 540 15
In the second case
A = [0,540];
B = 15;
A = [A B]
A = [A B]
A =
0 540 15

There are general methods available. You need to read the documentation at the links I provided in the answer.

Excuse me, but your method of creating a collection by defining it in terms of parts of other collections, if you tried to put that in a loooooong forloop, you would end up with an absolutely apauling time complexity to finish execution. While you are techinically correct that your method works, it has such a terrible time complexity that obviously it could only be used for relatively small collections. if instead one of the arrays had a dimension beyond n = 10000, well good luck running this algorithm...

v = 1:10; %new vector
i = 5; % index to insert
b = 15; % the number you want to insert
v = [v(1:i-1) b v(i:end)] % insert
