How can I find the template for the predefined environment: "CartPole-Discrete"

To load this environment into matlab I can use this line of code:

env = rlPredefinedEnv("CartPole-Discrete")

The problem is, I am trying to make the same exact environment by creating a template using this mathworks link. When I try to load it and train a rl network it has problems plotting each iteration.

I was hoping instead I can find the actual template for these predefined environment to make my life easier.

The end goal is just learning how to make custom environments for my own projects.

The predefined environments are coded in an object-oriented way, so you may not find all the info in one file. I would start with the following:

edit rl.env.CartPoleDiscreteAction

I found the files by typing

"edit rlPredefinedEnv"

into the command line.
