Unrecognized function or variable 'fitrnet'.

I have "Statistical and Machine Learning' package in my Matlab. But I can't use "fitrnet" function as introduced here https://www.mathworks.com/help/stats/fitrnet.html.

My code is as below:

cvp = cvpartition(n,'KFold',7);
CVMdl = fitrnet(PhyChemParams,'ARcoeff','CVPartition',cvp,'Standardize',true,'LayerSizes',[20,10]);
yfit = kfoldPredict(CVMdl);
mse = mean((yfit - CVMdl.Y).^2);

The error message is as below:

Unrecognized function or variable 'fitrnet'.

fitrnet was introduced in R2021a. Ensure you have the correct release installed, and that you have the statistics and machine learning toolbox installed.
