reduce rows of a due to b

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?

Expected result?

c = [0 1 0
     1 0 1];

Sorry to include it

Answer 1

[madhan ravi]

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

[JL]

Is is possible to get this?

c = [0 1 0
     1 0 1];

You can simply use setdiff with the rows option ...

c = setdiff(a,b,'rows')
