variable size 2D arrays

[BorisMoto]

Good afternoon everyone.

I need to allocate array of buffers (arrays). Each buffer would be different size. When implementing this in C/C++ it would look like an array of pointers where each pointer would point to a specific array. Each array could be NULL terminated to know exactly where it ends.

How can I implement this in LabVIEW? Two dimentional arrays are an option, but would waste a lot of memory since the second dimmention would have to be the dimmention of the largest buffer.

Please help.

Thank you in advance,

Well, you can use an array of clusters, where each cluster holds a 1D array. I think this would take less memory but it would definitly be more complex becuase you're adding the cluster operations. To do this, create a 1D array, drag it into a cluster and drag that cluster into another array. It's possible that this isn't any better. You can measure the performance difference by using VI profiling (Tools>>Advanced) and by using timing (the time the VI stopped minus the time it started).

Another option I can think about is using a 3D array. It looks like when you use this array, each page is dealt with like a seperate 2D array, so if you use only the first column (0) of each page, you can "skip the second dimension" and work only with the first and third.
