This is very useful ... and very efficient, so thanks again for your creativity.


@Carl Love 

I appreciate the quick response.

Using the procedure, AssignToClusters(U), I can see how many points are associated to each cluster but I still cannot obtain their coordinates. Can you tell me what I am doing wrong? 

Thank you.

@mehdi jafari 

Thank you ... that's a nice formulation.

I appreciate the help.


Yes - that did the trick!

Thanks for your help. I appreciate it.


Thank you for the timely help. I appreciate it.

Do you know of any way to change one of the functions to display as an animated column chart?


Yes - the example is indeed trivial (deliberately).

Sorry for the confusion - you have certainly addressed my query, so many thanks for these methods.




This is a great addition to my arsenal! Thanks for sharing.


Thanks so much ... that did the trick!


Thanks for your kind efforts in getting me sorted. I love that approach. Now I can go to work!


Thank you - I tried looking this up to no avail.



Many thanks for this. Really interesting solution.

When I run this workbook on my machine (Maple 2018), I get an error message: Reserved word 'local' unexpected.

Perhaps this is related to different versions used?



Thanks so much ... a really nice routine ... the use of the sequence function is elegant.

Can you also suggest an approach to obtain the midpoint / centroid of each internal grid? 


@Carl Love 

Thank you. I'll try that approach ..

@Carl Love 

Each point is assigned a weight but the weight does not need to be unique to any point - in fact, thinking about this further, points may have common weights. I wanted to ensure that weights are not necessarily equal at each point in the scatterplot and so the question you asked is indeed valid. I apologise for not being specific here.


@Daniel Skoog 

This is useful - I appreciate the steer. This subject appears to be very interesting  - perhaps, fascinating ... I'm just beginning to touch the surface.

If I have the good fortune to advance this to the weighted cluster problem, I'll post my findings here.

You have my thanks.
