why no "similarity matrix" option?

There doesn't seem to be an option for creating a dendrogram using a similarity matrix as the input data. The only option is to use a "distance matrix." My only solution to this problem is to create a new matrix using 1-x for each cell and then to change (reverse) the axis labels on the dendrogram. But it seems to me that adding the option of using a similarity matrix would not be difficult and would be very useful to many people.


  • We will look at adding this in time for the next release (Version 1.5)


  • This has now been implemented and will be available in Version 1.5. If anyone needs access to this feature before the release of version 1.5 then please email a request to support@statistixl.com.
