algorithm in c-code

[DFGray]

An added advantage of LabVIEW is that it is easy to produce multi-threaded programming to simultaneously process multiple data streams while acquiring data in real time.  LabVIEW takes care of the threading issues.  You only have to write the algorithm.

Of course, this also opens you up to all sorts of race conditions, but that's another topic...

thanks for all your help!

I understood that I will have to work with pointers in  C, because I will have to deal with 2D arrays.
To practice dealing with 2D-arrays I tried to write a dll that adds two 2D-arrays.

In the example I found in Labview they multiplied a 2D-array with itself, but to add two arrays and return it in a new array is something different.
It just doesn´t work out.

I attached the code I tried to use and a screenshot of the blockdiagram.

Where is my mistake?

Thanks a lot!
