Hello everyone,
I have an issue with my code. I want to use recursively the new values of a and b created in if or elseif staments. I thought that I can use a for loop but I couldn't write the boundaries of it. My start position is (20, 70) and my goal position is (60, 40), so when a=60 && b=40 I want to end the code. But as I said the a value and the b value does not gradually increase. For example for a it starts from 20 to 19, later 18, later 19, later 20, later 21, etc. depending on the Utot values. Can you please help me how can I use these values recursively and plot these? Thank you.
a=20;
b=70;
A11 = Utot(a-1,b-1);
A21 = Utot(a,b-1);
A31 = Utot(a+1,b-1);
A12 = Utot(a-1,b);
A32 = Utot(a+1,b);
A13 = Utot(a-1,b+1);
A23 = Utot(a,b+1);
A33 = Utot(a+1,b+1);
xd=[A11 A21 A31 A12 A32 A13 A23 A33]
if min(xd) < Utot(a, b)
[minValue, indexOfMinValue] = min(xd)
if min(xd)==A11
plot([a, a-1], [b, b-1])
a=a-1;
b=b-1;
elseif min(xd)==A21
plot([a,a], [b, b-1])
a=a;
b=b-1;
elseif min(xd)==A31
plot([a, a+1], [b, b-1])
a=a+1;
b=b-1;
elseif min(xd)==A12
plot([a, a-1], [b, b])
a=a-1
b=b
elseif min(xd)==A32
plot([a, a+1], [b, b])
a=a+1;
b=b;
elseif min(xd)==A13
plot([a, a-1], [b, b+1])
a=a-1;
b=b+1;
elseif min(xd)==A23
plot([a, a], [b, b+1])
a=a;
b=b+1;
elseif min(xd)==A33
plot([a, a+1], [b, b+1])
a=a+1;
b=b+1;
end
end
