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
