error permuting matrix rows

[Mychelle]

Hi

Ive tried to create a VI which randomly permutes rows of a matrix (the matrix is the input/the subvi), but

labview shows me an error, saying that Ive connected terminals of two different types - athough both are long.

Can someone tell me, whats wrong with my vi?

I would be greatful.

Thanks,

Mychelle

The terminals are not both long, you're trying to connect an array of long to a long.

so what exactly (and how) shall I change it?

Here is a way to swap two rows in an array.

thanks a lot, could you maybe be so kind and upload the VI?I just dont find the same icons for the

array methods you used (maybe due to different labview versions?).

thx

..sorry, I was first using firefox and so didnt see, that you can use the snippet..

 The image above is a snippet and contains embedded LabVIEW code. Simply download the image and then drag it into the diagram. It will turn into runnable code.

(EDIT: Ah, I see you noticed. Anyway, "index array" is resizeable, so there is no need for two instances as in Ben's example.)

If you have a newer version of LV,  wouldn't it be cleaner to use some of the newer memory structures like in place element and swap values?

 The OP want to swap entire rows in a 2D array. The in place element structure currently only supports single elements.

You're right.  I failed to notice that the wire coming out of it was thin as in scalar.
