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:length(X)
if ((x > X(i)) - (w/2)) & ((x < X(i)) + (w/2))
if ((y > Y(i)) - (h/2)) & ((y < Y(i)) + (h/2))
reach_target(i)=1;
end
end
end
Thanks very much!
