Get the values of an array from indices in another array: Matlab

Question

I have a 20x1 double array A, and a 1000x1 double array B.

I want to get array C, where array C will be 1000x1 doubl

Answer 1

I did it using for loop as shown below, not sure if this is the ideal solution:

C = zeros(1000,1);

for i = 1:1000
    C(i,1) = A(B(i));
end
