How to remove repeating entries from a vector?

How do you remove repeating entries in a vector?

For example: A = [1 1 1 0 0 1 1 1 1 0 0 0 0 0] should return B = [ 1 0 1 0].

The unique function does not do this from what I can tell. For the above example, it would return [0 1], which is not what I want.

Are the values always 1s and 0s? Or could you have something like [9,9,9,4,4,6,6,6,1,1,0,2,2]? If the latter would the result be [9,4,6,1,0,2]? What's the use case? Why do you need it? Is it your homework?

A = [1 1 1 0 0 1 1 1 1 0 0 0 0 0];

starts=groupLims(A);


B = A(starts)

B =

1 0 1 0
