Unrecognized function or variable 'knnimpute'

2 views (last 30 days)
I have the stats and ml toolboxes installed, as well as the bioinformatics toolbox as well. If I try to run the function on an incomplete matrix I get the error in the title.
data = [2 3 3; NaN 5 4; 4 2 NaN];
knnimpute(data)
How do I go about debugging this? I'm not familiear with matlab toolboxes, so I wasn't sure if they get automatically added to path or not.
OS is Arch running XFCE4, matlab release 2023b though that's probably not necessary information. Will update

If you installed the Toolboxes using the installer, MATLAB should be able to access them.
Your posted code works here —
data = [2 3 3; NaN 5 4; 4 2 NaN];
knnimpute(data)
ans = 3×3
2.0000 3.0000 3.0000 4.5000 5.0000 4.0000 4.0000 2.0000 2.0000
You may have a path problem.
Run these from a script or your Command Window:
restoredefaultpath
rehash toolboxcache
then see if it solves the problem. If it does not, then Contact Support.

This worked, I suspected it was a path issue but didn't know how to reset it. Thank you
