R2018a contained wlan example code, but none of it is in R2019b. What happened to all the wlan example code?

There was a wide selection of helper functions that just disappeared in R2019b that were in R2018a. Do you have anything that can help identify if these functions still exist, name changes if any and where they functions went?

There is a bunch of examples here: <https://de.mathworks.com/help/wlan/examples.html>

[Bruce Tibbetts]

That is helpful. Thanks. My main concern is that I have a functioning program that worked in R2018a that is now completely broken and no clear path on how to get it back to functioning in R2019b.

Since i dont have access to this Toolbox i only can give you the advice to share your Code and tell exactly what the problem is you have. Maybe someone can help to fix your code.

One function I can't seem to find anymore is heLTFChannelEstimate. HE-LTF just disappeared.

what about <https://de.mathworks.com/help/wlan/examples/802-11ax-packet-error-rate-simulation-for-single-user-format.html?searchHighlight=heltfchannelestimate&s_tid=doc_srchtitle#d117e2020>

I believe the examples were reorganized at some point in the last few releases so that helper functions (which are specific to the examples) are no longer on the MATLAB path by default but are still accessible to the examples.

If you open an example that has hyperlinks to the helper functions at the end (like the 802.11ax Parameterization for Waveform Generation and Simulation example) as a Live Script clicking the links will open the helper functions. Alternately if you open that example in the Editor using the command openExample('wlan/HEParameterizationExample') the directory that contains the main example file should (at least it does for this example) contain the helper functions.
