Hi
I have 2 vectors and I want to merge them directly. A=[1;2;3;4;5] and B=zeros(17,1) where, elements of A are going to these indices [4 5 7 11 13];
A_new=[0;0;0;1;2;0;3;0;0;0;4;0;5;0;0;0;0]

One way:
B = zeros(17,1);
A = [1;2;3;4;5];
I = [4 5 7 11 13];
A_new = B;
A_new(I) = A;

That isn’t the same as in your original Question.
You have to address them by the appropriate subscripts, and it works:
aa = [1 2 3 4];
bb = [100 100];
cc = aa;
cc(1:2) = cc(1:2) + bb;
There may be other ways, but that’s the most efficient.
