How to sort and split arrays into new cluster-array?

[OnlyOne]

Hello,

i have three arrays A (integer), B (timestamp) and C (double).

Now i want to convert them into a cluster array. The size of the cluster-array is the number of different values in array A (here: two different values 1 and 2)

So index 0 of the cluster array contains integer 1 and two arrays with all values of the other two arrays where the index of array A is 1.

Index 1 of the cluster array contains integer 2 and two arrays with all values of the other two arrays where the index of array A is 2.

How can this be done?

Thanks and best regards

Something like this?

No, the array-size of the output array equals the size of different numbers in array A.

In your screenshot the values of  B and C in index 2 should appear as array under index 0 as they have the same number in A.

A:

1

2

1

2

B

2009

2010

2011

2012

C

10

11

12

13

Cluster[0]

1

Timestamp[2009,2011]

Value[10,12]

Cluster[1]

2

Timestamp[2010,2012]

Value[11,13]

The values in A are not always in a order. They can be mixed like [1,2,1,2,1,1,1,1,2,2,1,2,1,2,2,2,2,1,1,1]

Here's a simple solution that uses the OpenG array tools.

Hi jcarmody,

where did you get this library? I just downloaded my version from http://lavag.org/files/file/169-openg-array-xnodes/ but i have different in/outputs of the vis...

Thx

here my (not so flexible) solution using conditional indexing ...

I canceled my first try , so I thought I should provide at least another solution 😉

Install the OpenG Package with the help of the VI Package Manager.
