Say I have a vector V, and a set A whose elements are indexes.
How to show elements of V excluding indexes from A?
Example: V={1 4 6 5 8 11 25 36} A = {2 3 6}
I need to display {1 5 8 25 36}.
I know I can make them zero or remove them. But I don't want to do that way because I will use them later, also I want to display several times so it's bad to change the size or those values.
Thank you.

setdiff(V,V(A))
will give you the vector that you want. This will work when V and A are vectors and not cell arrays (you are using {} which will make V and A a cell array. Use []).|

for i = 1:length(A)
idx = A{i}-i;
V(idx) = [];
end
