[Octave-bug-tracker] [bug #61744] [octave forge] (statistics): dendrogram demonstration #5 incorrect result

[Liang Tang]

Follow-up Comment #3, bug #61744 (project octave):

Thanks.  

There is one related item still confused me.  The document says: 

The number of leaves shown by the dendrogram plot is limited to p. The default
value for p is 30. Set p to 0 to plot all leaves. 

What it did not say is if we have input tree dimension higher than 30 and p is
not set to zero, what does the plot actually show?  if the plot is not showing
the correct information, then the combination of input tree higher than 30 and
p~=0 should be an error.  

With the current implementation, I think there are only two legal
combinations: 

input<=30 and no change to default p
input>30  and p=0

The existing code would accept input>30 with default P and then show some tree
plot which looks incorrect to me.
