Hello. Didn't find a relevant answer.
Suppose we have an array of such form:
A=[a1 b1 c1 d1; a2 b2 c2 d2; etc], i.e. rows of sets of parameters. How to delete from the array the rows with the following conditions:
if 1)a1+b1<c1 then delete that row
and 2) if a1+b1>d1 then delete that row
end
Thank you!

A(A(:,1)+A(:,2) < A(:,3) | A(:,1)+A(:,2) > A(:,4), :) = [];
