Create the following vector using a while loop

Hello, I am taking an introductory ENGR course this semester.

I am studying a while loop in MATLAB, however I don't understand how to create the code for a problem.

Create the following vector B = [4 8 12 16 20 24] Using a while loop. The while loop must create the vector and add an element to it each time it passes through the loop.

Could you offer me the answer with some comments?

Answer 1

[KSSV]

N = 6 ;  % length  of vector
% while loop
B = zeros(1,N) ;
B(1) = 4 ;
count = 1 ;
while count < 6
    count = count+1 ;
    B(count) = B(count-1)+4 ;
end

%%no loop
C = 4:4:24 ;

%%using for loop
D = zeros(1,N) ;
D(1) = 4 ;
for i = 2:N
    D(i) = D(i-1)+4 ;
end
