If you are going to learn LabVIEW, then learn LabVIEW -- there should be no "Matlab Script" in your code (it is much more complicated dealing with two programming paradigms that have different ways of representing data, arithmetic, etc.).
Here are a few questions and assumptions:
- I assume your "input" is an array of 6 integers, 1 through 6, [1, 2, 3, 4, 5, 6] symbolically.
- What is your output? Is it a single Array of 6 integers, a "random permutation" of the input array, e.g. [4, 2, 5, 6, 1, 3]? Or is it a two-dimensional Array, each element of which is a different permutation of the original 6-element Array?
Point #1 is my assumption. #2 gets to the heart of the question, What are you trying to do? The method(s) to solve each of the two #2 tasks have approaches with similarities and differences!
Whatever the task, it is going to involve choosing particular elements of an array and using them to construct another array. Practice with pencil and paper and an initial array of [1, 2, 3] (you should be able to write down the six permutations, starting with the "identity" permutation [1, 2, 3] -- see if you can arrange them in a pattern (there will be several possible) and then deduce a "rule" for going from one pattern to another. Test it out with [1, 2, 3, 4], then code it in LabVIEW for [1, 2, 3, 4, 5, 6].

P.S. -- this problem can be solved with a "recursive VI", one that calls itself, which LabVIEW allows, but is a semi-advanced topic. Ask your instructor about LabVIEW recursive VIs and revisit this problem at the end of the course.
