A=[-1,1,1;0,-1,0;0,0,-1;1,0,0];
blnA = logical( A == -1 );
blnOut = find(all(ismember(A,[0,-1]),2));
(Now i chose row 3) 0,0,-1
and how can i find a column which is including 1 and refering to that row 3's -1
( in that matrix column 3 must be chosen)

negcolumn = find(A(ThisRow,:) == -1);
onerow = find(A(:,negcolumn) == 1);
A(onerow, negcolumn) %crosscheck
