Hello,
For your first problem:
RLC is a 1 by 4 vector and so to access its elements you use RLC(i) with i in [1,4].
In your if conditions line 137:
if RLC(j-1) < RLC(j) && RLC(j) < RLC(j+1)
When j = 1 you compare RLC(j=1) with RLC(j-1=0) (left side of the &&), the latter does not exist as the index must be in [1,4], you avoided it with your if at line 132:
if j == 1
Kb = Kb_Min;
end
Now you need to do the same thing when j = 4, otherwise you will compare RLC(j=4) with RLC(j+1=5) (right side of the &&). Use elseif for that.
I didn't check the whole file, but you will have to do the same thing for all other conditions where you make comparison using index such as i+n or i-n (as you did line 97 for instance with RLC(j-1) and RLC(j+1)): you must ensure that i+n and i-n are superior or equal to 1 and inferior or equal to vector length (same applies to matrix, arrays ...) .
I can't help you on your second problem as I'm on matlab R2022b and app was coded in R2023.
