MATLAB: How to display entries of a vector with exclusion

Question

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.

Answer 1

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 []).|
