remove the frequent values withou sorting

hello

I need a function remove the frequent values(keeping the first appearance of value) without using unique because it is making sortg

For example

x=[3 4 3 5 1 0 4 2];

I need x to be

x=[3 4 5 1 0 2]

Thanks in advance

You can still use unique:

x = [3 4 3 5 1 0 4 2];
x = unique(x,"stable")

x = 1×6

3 4 5 1 0 2
