Hi, I am trying to model an intersection using different rules but I am having a hard time getting the thing to work in the simplest stage. I know there is probably an easier way to do this but I am trying to do it this way:(adsbygoogle = window.adsbygoogle || []).push({});

clear

grid=zeros(10,10); %grid creation

grid2=zeros(10,10);

grid3=zeros(10,10);

grid(1:4,1:4)=2; %empte spaces representing city blocks

grid(7:10,1:4)=2;

grid(1:4,7:10)=2;

grid(7:10,7:10)=2;

grid(6,2)=1; %initial grid coords for cars

grid(6,4)=1;

grid(7,6)=1;

grid(5,7)=1;

grid(5,9)=1;

grid(4,5)=1;

grid(2,5)=1;

grid(9,6)=1;

tfinal=100;

for t=1:10

random=randi(10,1);

if grid(6,10)==1;

grid2(6,10)=0;

end

if grid(6,9)==1;

grid2(6,10)=1 & grid3(6,9)==-1;

end

if grid(6,8)==1;

grid2(6,9)=1 & grid3(6,8)==-1;

end

if grid(6,7)==1;

grid2(6,8)=1 & grid3(6,7)==-1;

end

if grid(6,6)==1;

grid2(6,7)=1 & grid3(6,6)==-1;

end

if grid(6,5)==1;

grid2(6,6)=1 & grid3(6,5)==-1;

end

if (grid(6,4)==1) && 0<t<=(tfinal/10)

grid2(6,5)=1 & grid3(6,4)==-1;

end

if grid(6,3)==1;

grid2(6,4)=1 & grid3(6,3)==-1;

end

if grid(6,2)==1;

grid2(6,3)=1 & grid3(6,2)==-1;

end

if grid(6,1)==1;

grid2(6,2)=1 & grid3(6,1)==-1;

elseif grid(6,1)==0 & random>=5;

grid2(6,1)=1;

end

grid2=grid3+grid2;

grid=grid2;

end

This is just the first of 4 aspects of the intersection node. I want the cars to move ahead in each column, except a time limitation on column 5 representing the signal. This is my first time using & for anything in matlab, and I have a feeling not understanding its use is causing me problems. I have been trying for a while and I am just plain stuck now. Anyone have any suggestions?
