What are all of these and should they be here?

whos
  Name              Size            Bytes  Class             Attributes

  ans               1x1                 8  double                      
  cmd               1x1               294  string                      
  cmdout            1x33               66  char                        
  gdsCacheDir       1x14               28  char                        
  gdsCacheFlag      1x1                 8  double                      
  i                 0x0                 0  double                      
  managers          1x0                 0  cell                        
  managersMap       0x1                 8  containers.Map              
  mshDir            1x18               36  char                        
  prefDir           1x1               170  string                      
  status            1x1                 8  double                      

In particular, having an empty double named 'i' is not good as that can screw up code by shadowing the built-in function i that returns sqrt(-1).

which i
built-in (/MATLAB/toolbox/matlab/elmat/i)

I reported the i situation several months ago.
