Hello All,
I am trying to use feature selection with KNN classifier
fun1 = @(XT,yT,Xt,yt)... (sum((yt ~= knnclassify(Xt,XT,yT)))); [fs,history] = sequentialfs(fun1,XT,yT,'cv',c1,'options',opts,'direction','forward')
But, I am getting an error which says knn classify is not a valid function. Can you suggest any solution for that?

Is it on your path? It seems to need the Bioinformatics Toolbox, though you haven't added this to the Products list so I don't know if you have this toolbox or not?
Type:
which knnclassify
to see if it is on your path.
