How can i find deleted rows from matrix??

1 view (last 30 days)
x0 = [2 3 2 2 2;
2 3 2 2 2;
2 4 1 2 2;
2 4 1 2 2;
2 3 2 2 2;
2 3 2 2 2];
x0(any(x0<2,2),:) = [];
x0 = [2 3 2 2 2;
2 3 2 2 2;
2 3 2 2 2;
2 3 2 2 2];
I want to see deleted row separately i.e
2 4 1 2 2;
2 4 1 2 2;
I want to know index of x0 which deleted.

use k = x0(any(x0<2,2),:) ;
k will be your matrix which you are going to delete.

Save the index and use it:
>> idx = any(x0<2,2);
>> xdel = x0(idx,:)
xdel =
2 4 1 2 2
2 4 1 2 2
>> xnew = x0(~idx,:)
xnew =
2 3 2 2 2
2 3 2 2 2
2 3 2 2 2
2 3 2 2 2
