I recently downloaded R2016a. Unlike before I have problems with gscatter. The help contains the example:

       load carsmall
       gscatter(Weight, MPG, Origin)

It returns an error:

Undefined variable "statslib" or class "statslib.internal.mgrp2idx"

I am using the default path. Do I miss some toolboxes?

In R2016a I find this:

   >> which statslib.internal.mgrp2idx
   ...\matlab\toolbox\shared\statslib\+statslib\+internal\mgrp2idx.m  % static method or package function

and this:

   >> ls(fullfile(matlabroot,'toolbox','shared','statslib','+statslib','+internal'))
   .                      getParamVal.m          isScalarInt.m          parseOnOff.m           
   ..                     grp2idx.m              isString.m             plotGroupedHist.m      
   colorStringToRGB.m     hasMissingVal.m        mgrp2idx.m             removenan.m            
   cycleLineProperties.m  isIntegerVals.m        parseArgs.m

and this:

   >> findstr(path,'statslib')
   ans =
          11801       11891

Would you check to make sure 'statslib' can be found in your path, the contents of the directory are correct, and the 'which' command finds this file?

Hi,

Have you installed the Statistics and Machine Learning Toolbox as well in the newer version?

You can check the output of the 'ver' command to check the list of toolbox's you have installed. If you are using a network license you use 'license checkout statistics_toolbox ' to verify if you are able to use the toolbox.

You can also use the 'gscatter' command and then use the 'license inuse' to check if the Statistics toolbox is being used.

Hope this helps

regards

Rakesh
