Hi everyone, I have 2 matices, A and B
a = [0 1 0
0 1 1
1 0 1
1 1 1];
b =[1 1 1
0 1 1];
Is it possible to reduce a using b?

ix = ismember(a,b,'rows');
a(ix,:) % gives you the rows in a which is common to b and ~ix vice versa

You can simply use setdiff with the rows option ...
c = setdiff(a,b,'rows')
