Trying to be as general as p[ossible, try this:

% Define initial vector:
v = 1:14
% Get everything except for certain values:
v2 = setdiff(v, [1,4,5,6,8])
% Get up to 5 randomly located indexes of v2.
numElements = min(5, length(v2))
indexes = sort(randperm(length(v2), numElements))  % Sorting is optional
% Get the values at those indexes (will be the same for this simple example, but not in general).
values = v2(indexes)

You'll see

v =

1 2 3 4 5 6 7 8 9 10 11 12 13 14

v2 =

2 3 7 9 10 11 12 13 14

numElements =

5

indexes =

1 2 4 6 7

values =

2 3 9 11 12
