No. Sorry, but no. You cannot use functions from one release in another release. They essentially check for this.
Could you write codes with those names, adding them to your own toolboxes? Well, yes. But then you would need to write the code yourself.
Having said that, I know that unwrap has certainly been around for ages. A quick check tells me it was introduced before 2006a. So at least 16 years ago, and I recall it before then.
As far as wrap goes, it does not exist in MATLAB R2020b, then I checked R2021a. Not in there either. I guess this means it is time to install a new release for me. Ok. Checked. wrap does also not exist in R2021b, update 2, either. So unless you have this toolbox:
which wrap -all
then you will not have wrap. Are you a wrapper? Is it my birthday already? ;-)
