I want to make one value of a variable in a for loop dependent on the value of another variable 2 timesteps ago.
When I am on t=1, the code will lookup Variable(-1) which is an invalid index number because array index numbers must start at 1.
Is there a way to say?
if variable(x) has an invalid reference number do y?
Can you please give me an example?

This is a simplified version of my problem.
for(t=1:10),
Array1=[1 4 5 6 7 8 9]; Variable=(Array1(t-1))
end
The error is: Attempted to access Array1(0); index must be a positive integer or logical.
I want Variable to simply skip t's or return some specific value where the index is bad
