delete certain rows from a matrix

I have two matrices and want to delete the rows of the first matrix which are identical to particular rows of the second matrix. For example, I have q = [1 0 0 0; 2 3 4 5; 6 7 8 9] and w = [1 0 0 0]. I want a generic command for q to become [2 3 4 5;6 7 8 9] , i.e., delete [1 0 0 0] from w

Answer 1

[Azzi Abdelmalek]

q = [1 0 0 0; 2 3 4 5; 6 7 8 9] 
w = [1 0 0 0]
q=setdiff(q,w,'rows')

or

q = [1 0 0 0; 2 3 4 5; 6 7 8 9] 
w = [1 0 0 0]
q(ismember(q,w,'rows'))=[]

Answer 2

setdiff(q,w,'rows','stable')

Answer 3

If preserving repeated rows q(i,:) is important, then,

idx=all(   bsxfun(@eq,q,w), 2);

result=q(~idx,:);
