Select a set of variables from an array NOT equal to a set of indices

I need to select all of values in an array except for specified indices.

       A=[1 2 3 4 5 6 7 8 9];
       set=[1 3 5];
       B = A(~set); %this is the issue

I want to get a new vector which contains all of the values of A except for indices 1 3 and 5. So the output would be

       B=[2 4 6 7 8 9];

Appreciate the help.

Reid - how about trying

 B = A;
 B(set) = [];

and those elements at indices 1,3,5 should now be removed from B.

B = A(setdiff(1:length(A), set))
