Remove a row from an array

I have a two sets of coordinates, and need to exclude one set from the other. Here 'grid' & 'yx' are the two lists. How would I remove all 'xy' coordinates from 'grid'?

x = [1,1,1,1,1,1,2,2,2];
y = [1,1,2,1,1,2,1,1,2];
n = 1:12;

yx = [y',x'];

[gx,gy] = meshgrid(n,n);
gxy=cat(2,gx',gy');
grid = reshape(gxy,[],2);

I don't quite understand.

Do you mean that if a row from grid also appears as a row in yx, then that row should be removed from grid? If yes, then ...

grid(ismember(grid,yx,'row'),:) = []

Yes, that is what I was trying to describe. Thank you!
