[Octave-patch-tracker] [patch #9989] [statistics] improve the compatibility of 'linkage'

[anonymous]

Follow-up Comment #2, patch #9989 (project octave):

I think there must be a mistake. The patch I submitted removes that condition
check on d:


   if (isempty (d))
     error ("linkage: d cannot be empty");
-  elseif ( nargin < 3 && ~ isvector (d))
-    error ("linkage: d must be a vector");
   endif


Actually, after applying the patch, you should be able to run:

>> X = rand (20000, 3);
>> Z = linkage (X, "ward");


That is exactly the main problem I tried to overcome with this patch. The
other one being the "savememory" option.
