Standardization of KNN Variables

When I try to follow the API for fitting data to a KNN model (<http://uk.mathworks.com/help/stats/fitcknn.html)>, it uses the code "Mdl = fitcknn(X,Y,'NumNeighbors',5,'Standardize',1)" but "'Standardize',1" is apparently not a valid parameter name. Can anyone shed some light on this?

Kind regards Jason

This was added to the fitcknn function in R2014b. If you are using a previous version then you do not have access to this Property. You can check this with:

ver

The website always maintains the documentation of the latest version (currently 2015b). I suggest for older versions you consult the documentation provided with the software:

doc fitcknn % Will give you documentation for your version.

That's great, thanks!

Would you please explain this parameter, namely "Standardize"? and when is it recommended to be used?
