Hi. I'm struggling with how to make my code.

Here is the thing. I want to get a new matrix A such that all duplicated vectors are removed. Here is my matrix A and a new matrix A that I want to get:

A = [1 3; 1 4; 1 3; 1 4; 2 3; 3 4; 3 4; 3 5; 4 5]

new A = [1 3; 1 4; 2 3; 3 4; 3 5; 4 5].

How to write the code to get new A...? I'm trying to make it as a function, however, I don't have clear ideas...

I need some help! Thank you so much!!

在 MATLAB Online 中打开

A = [1 3; 1 4; 1 3; 1 4; 2 3; 3 4; 3 4; 3 5; 4 5];
new_A = unique(A,'rows')
new_A = 6×2
     1     3
     1     4
     2     3
     3     4
     3     5
     4     5
