What toolbox is required for allpaths() built-in command?

I found out that there is an in-built command to find possible paths between two nodes in a graph.

paths = allpaths(G,s,t)

But when I use it it says command not found. I am unable to decipher what toolbox I might need to install for this. Anyone please tell. This is the documentation page https://www.mathworks.com/help/matlab/ref/graph.allpaths.html

The surprising thing is the shortestpath command works fine. I assume these two commands fall in the same toolbox but then why allpaths isn't working?

The documentation looks, like allpaths belongs to Matlab's standard toolbox, but it was introduced in R2021a. Which Matlab version do you use?

shortestpath is existing sind R2015b.

Yes, I just figured that out. I was using 2020 version but I updated to 2021 and now it is working. Thanks. I knew that this function didn't exist and that's why I was using my own script. But today, I was taken by surprise when I saw the allpaths() documentation & decided to use this in place of my code.
