How to compare the the values of a 3-d dimensional array

Suppose I have a 3-D array, lets say, p(1,n,k) where n varies from 0 to t_span and t_span = 0:dt:80 (dt = 0.01) and k varies from 1 to 8.
Lets say I have an energy level denoted by E and decreasing at a constant rate in the following way:
E(1) = 6000;
E_lower = 4500;
E(n+1) = E(n) + dt * (-100);
What I want is, at the instant when E < E_lower, I want to compare the values between p(1,n,1) to p(1,n,8) and I want to know the index 'k' where the lowest value of p(1,n,k) is present at that particular instant "n".
Can anyone help me in this, how to proceed.
Thanks in advance.

As an index n must be a natural number, which is not the case here.
The smallest value of n or the value of n at the instant E < E_lower is, n = 1502, from the relationship you wrote.
Now we have to find the minimum of p(1,n,1:8). You can use the min for that, and obtain both the minimum value and the corresponding index.
