Deduplicate Rows from Struct

I have the following struct-

Database.x = [1 0 1
              2 0 2
              3 0 1
              1 0 1];
Database.f = [10 20
              20 30
              30 40
              10 15];

In Database.x, there are duplicate rows (1st and 4th one). I want to deduplicate them and based on that, I want to remove the corresponding row from Databse.f

How do I do this?

I want to remove the corresponding row from Databse.f

In referene to your example, how would you decide whether the first or fourth row of f should be removed?

[Rounak Saha Niloy]

Fourth row is to be removed.

How about this?

Database.x = [1 0 1
              2 0 2
              3 0 1
              1 0 1];
Database.f = [10 20
              20 30
              30 40
              10 15];

[Database.x,I]=unique(Database.x,'rows');
Database.f=Database.f(I,:);

Database.x

ans = 3×3

1 0 1 2 0 2 3 0 1

Database.f

ans = 3×2

10 20 20 30 30 40
