Functions are not defined in physics informed neural network documentation

Hello, I am using R2020a

In this document, many functions are not defined.

https://www.mathworks.com/help/deeplearning/ug/solve-partial-differential-equations-with-lbfgs-method-and-deep-learning.html

For example, in my R2020a

initializeHe, initializezeros they are not defined

And this one is very hard to fellow, I want to write a model on my local MATLAB, but copy&paste&learning is impossible, since many functions you just don't know what they are, and no results from help.

yes，sir， may be these function are self define，so may be upload MATLAB version to test again

According to the Release Notes this example was added to Deep Learning Toolbox in release R2021a. You will need to upgrade to that release or later to have access to the code for that example.
