Distance from x,y coordinates [Beginner]

Hello everybody, I have a small question:

I have two matrices: A(2099x2) and B(9x4).

Matrix A = trajectory (x,y coordinates)

Matrix B = X,Y coordinates of 9 targets (black square dots), the width=0.20 and the height= 0.20.

I would like to know if the trajectory (blue line) passes through the green area (green square) around the black square.

I'm working on a code but It doesn’t seem to work, any suggestions?:

reach_target= zeros(9,1);

for i = 1:9

    if A(1,:) > (B(i,1) - (w/2)) & A(1,:) < (B(i,1) + (w/2)) 

        if A(:,2) > (B(i,2) - (h/2)) & A(:,2) < (B(i,2) + (h/2))
           reach_target(i)=1;
        else
            reach_target(i)=0;
        end
    end
end
