I am receiving the appended error (untitled.jpg) when I run the code in the loop which is appended as a jpg (loop where error occurs.jpg). I am also attaching the plot permeability file for reference.

clc; clear all;
%define u
%define v
%L_i(x)=a_i(x)+b_i
format 'bank'
x=[1/4 1/2]
n=2;
for i=1:n
a(i)=x(i+1)-x(i)/0.5
end
why am i getting index exceed the number of arrays

@RAJESH: x has two elements. You try to access x(i+1) for i =1:2, but when i is 2, x(i+1) is x(3), which doesn't exist because x has only two elements.

The error means you are trying to index an empty array.
a = [];
a(1)
Index exceeds the number of array elements. Index must not exceed 0.
It looks like the line causing the error is from ChomboOutput
obj.levelArray(1)
You'll want to check that levelArray has been assigned values before indexing into it.
