Data transfer in for loop

Why does the program not jump into the second for loop? Why is there no data in the element? See Atachment
 
Thanks for your answers

Try Executed Highlighting (the ligh-bulb),  and see that the shift register is unitialized an uses an array of 0 elements.

Hi Irrenhaus,

and there are some more mysteries in your code:
1) you don't need the small inner for loops (those doing the minus/square/sqrt operation) - you can calc directly with arrays!
2) What's that square/sqrt operation? Replace it by an absolute function!
3) Now you should only have one for loop in your code: When there is an auto-indexing input you don't need to wire the loop count input (at least when the autoindexing should control the loop!)

Can you explain the algorithm you are trying to implement?

This code should be the implementation of a simple kmeans. Input dada is time and current measurement over one day and we want to cluster into about 7 clusters over the day. Output should be the mean level of the clusters.

Pleas help me.... Smiley Sad

Thanks!!!

Something along the lines of http://en.wikipedia.org/wiki/K-means_algorithm perhaps?
 
I would have never guessed from your code.
 
Where does the data enter the code??? Since you have a simple time series, do you only need a 1D kmeans?
 
Sorry, I don't have time to look into this, but maybe others will have some suggestions.
 
(RIght now your code runs forever using 100% CPU, while doing nothing useful ....)
