rocmetric 'Unrecognized function or variable 'rocmetrics'.'

I'm trying to get the ROC metrics for my multiclass svm but I keep receiving this error:
Unrecognized function or variable 'rocmetrics'.
I tried to use the documentation example:
load fisheriris
rng("default") % For reproducibility
Mdl = fitctree(meas,species,Crossval="on");
[~,Scores] = kfoldPredict(Mdl);
size(Scores)
Mdl.ClassNames
% Works until this point
rocObj = rocmetrics(species,Scores,Mdl.ClassNames);
% unrecognised function or variable 'rocmetrics'.
I'm unsure why this isn't working. I'm currently using Matlab R2021b.
What could I use instead to get the ROC and AUC if this function is no longer available?
Thanks in advance

I could not find "rocmetric" function in R2021b release documentation. So I think “rocmetric” function was introduced in the R2022a MATLAB release. Since you specified that you are using R2021b, you might be getting the above error.
As per my understanding, there is no complete alternative for “rocmetric” function in MATLAB for your release version, but you can go through the below documentation to understand it’s working.
