According to the help manual...

To perform an action when the data table is updated, click the data table, and then, from the Data Table context panel, select Edit Content Changed Code to open the Code Editor dialog for the data table.

I am unable to make this work, nothing happens when I click on that button.

Edit - Component code - shows everything greyed out.

Any hints?

Any idea why a similar indexing call to an Array and a Matrix gives different "orientations"?

The indexing call [1..2,1] to a Matrix gives a a column Vector, while a similar call to an Array gives a (row) Array. So somehow the Array call gives a transpose of the original.

I've got a question regarding sum of matrix or arrays.

My problem is that sum of the values of the maxtrices is not calculated, but shown as a sum with the '+' sign. I have tried to recreate the problem with an easier example, but so far I have not managed to do so.

Before posting the whole program, I'd like to post it as a question, if someone has an idea about how I could get an evaluation of the matrix.

Here's a screenshot.

Is there any possibility to update a DataTable, when the connected Array is expanded?

I've tried to change visibleColumns, but that doesn't show the content unfortunately.

I've somehow understood that sequences are extremly powerful so far. However I have to admit that they are quite complicated to read and understand, and I still am a bit confused how to work with them properly.

The attached example shows a very simple sequence.

My question is - how can I use its results further on?

What I for example would like to have, is a plot, where the first results in the array are the x- values, and the second are used as the y-values. Before that I need to extract both of them into vectors.

Could this be done in one operation, or can I somehow iterate throught the members of the returned values?
