Why does not the example of "Solve Partial Differential Equation with L-BFGS Method and Deep Learning" with fmincon exist anymore on mathworks web site?

Hello,
I have tried to reach the example of "Solve Partial Differential Equation with L-BFGS Method and Deep Learning" with fmincon but I could not find it anymore on the web site of mathworks and instead I found this example: https://www.mathworks.com/help/deeplearning/ug/solve-partial-differential-equations-with-lbfgs-method-and-deep-learning.html?searchHighlight=solve%20partial%20differential%20equations%20with%20lbfgs%20method&s_tid=srchtitle_solve%20partial%20differential%20equations%20with%20lbfgs%20method_1
Why was it removed? Was there a mistake in the example and the fmincon is not suitable for it?
Thanks in advance.

I do not know the reasons why the example was updated. Incidentally, you can still locate it in the R2022b version of the documentation:
The documentation does try to show recommended workflows, so my guess is that the example was updated to highlight a new way to solve this problem using functionality introduced in the latest release (R2023a), which does not require the use of fmincon.
