Re: Exporting 2d arrays

[Artur Nogueira]

Hi Marcus,

By "variable", it means "the size is set by the user once and doesn't change

during runtime" and, most importantly, it can change from one simulation to another. In my case, each output terminal from my Python Block is connected to a Frequency Sink and therefore it would be unpractical to remove or make new connections all the time. So I was wondering if it is possible to export a 2-d array in a single output terminal rather than exporting N 1-d arrays through N different ports (please find attached a pdf file with a simple illustration of my question). 

And, by the way, I also have a question regarding the second point that you've mentioned ("the same block outputs matrices of different length"), but we can discuss it later or in another occasion.

Best regards,

Artur

does "variable" mean the size is set by the user once and doesn't change
during runtime, or does it mean that the same block outputs matrices of
different length?

Another way of thinking about this would be:
Is this a block that really produces a _stream of identical items_ or is
it rather a block that produces _messages of different content_?

Best regards,
Marcus
