MATLAB: Getting elements of a vector

Question

I have this vector

g_counter = [5 6 9 0 0];
list = [1 2 3];

If I do

g_counter(list)

I get 5 6 9 instead I would get 0 0. I would obtain complementary elements

Answer 1

g_counter = [5 6 9 0 0];
out = g_counter(g_counter == 0);

or

g_counter = [5 6 9 0 0]; 
list = [1 2 3];
out = g_counter(setdiff(1:numel(g_counter),list));

or

g_counter = [5 6 9 0 0];
list = [1 2 3]; 
t = true(size(g_counter));
t(list) = false;
out = g_counter(t);
