Hello, instead of Python, I want to learn physics informed neural networks in MATLAB. I am using R2020a
https://www.mathworks.com/help/deeplearning/ug/solve-partial-differential-equations-using-deep-learning.html
Like there is no function called initializeHe, initializezeros, etc
I found this tutorial, but I just cannot follow it. What I suppoesed is to have a complete code, then I can make breakpoints, etc to learn it. However this one too many jumps, just don't know where I should look.
Can anyone help me?

What version of MATLAB are you using? There is a function called arraydatastore.
Did you try opening the full script in MATLAB and running from there?

I had same issue. I resolved it by installing the deep learning toolbox of MATLAB.

I had the same problem. I solved it with adding the following functions:
function parameter = initializeHe(sz,numIn,className)
arguments
sz
numIn
className = 'single'
end
parameter = sqrt(2/numIn) * randn(sz,className);
parameter = dlarray(parameter);
end
function parameter = initializeZeros(sz,className)
arguments
sz
className = 'single'
end
parameter = zeros(sz,className);
parameter = dlarray(parameter);
end
