MATLAB: Which function should I use here to group the matrix

groupingmaker

So let's say I have this matrix in Matlab.
A = [1 0 0;
2 0 0;
1.1 0 0;
2.1 0 0;
1.2 0 0;
2.2 0 0]
The thing is in my case, the values of row 1,3 and 5 are same and values of row 2,4 and 6 are same. And I want to write my new matrix like this.
B = [1 0 0;
1.1 0 0;
1.2 0 0;
2 0 0;
2.1 0 0;
2.2 0 0]
Someone can help me, what function should I use here. I beleive this is something related to group function, but didnt findout able to anything which I can use.
Appreciate your help,
Thank you :).

Use sortrows()
  
A =   [1 0 0; 
       2 0 0; 
       1.1 0 0; 
       2.1 0 0;
       1.2 0 0;
       2.2 0 0]
   
  B = sortrows(A)
