If I have a matrix of xy coordinates A where A is something like
A= [1 2
3 4
3 0
10 1
3 11
5 6
.
.
.
x y ]
and I want to remove all data entry points where x>5, and y>4. How might I do that effectively without previous knowledge of the entries (i.e. x and y = 10*rand(n,1) or something)?

[i,~] = find(A(:,1) > 5 & A(:,2) < 4);
A(i,:) = []
