How to clean up the repeating element in an array?

I have a variable x = [0 0 0 0 2 2 4]

I want to create another varible v that stores only the different element inside x which mean v = [0 2 4]

How to do that?

x = [0 0 0 0 2 2 4]

x = 1×7

0 0 0 0 2 2 4

v = unique(x)

v = 1×3

0 2 4

Thank you. May I ask if it is possible if I want to keep the repeating element in its order?

I tried x = [ 0 0 2 5 1 1]

and v = unique(x) = [0 1 2 5]

But I want v to store as v = [0 2 5 1]

[Walter Roberson]

x = [ 0 0 2 5 1 1]

x = 1×6

0 0 2 5 1 1

v = unique(x, 'stable')

v = 1×4

0 2 5 1
