[Andreas Goser]

This command was introduced in R2018a. I suggest you install R2018a or b in parallel to your R2017b installation and test.

[Steven Lord]

Andreas is correct. For most or all functions introduced since R2015a, if you look at the end of their documentation page in the online documentation they will indicate when they were introduced (or will indicate they were introduced prior to release R2006a.)

For cwtfreqbounds that message states "Introduced in R2018a".

[Ritabrata Thakur]

Thanks for letting me know. Will do the same.
