Where is the function ismat?

Hello-

I just downloaded 2021a with all 92 toolboxes and am still getting the following error:

Unrecognized function or variable 'ismat'.
Error in buildgrid (line 59)
  if ismat(X),	X=mat2vec(X);		end

Error in bin1d (line 42)
[X,XG]=buildgrid(X,x);		% buildgrid also filters for matrix input

Can someone post the m file or tell me where to find the internal function ismat?

Thanks!
