2D double array shared variable in real-time application

[alex b.]

Hi,

I am using Labview 8 and I created a real-time application using shared variables. Is it possible to create a 2D array of double (I don't find how to do itdirectly). Probably I can define my own control and load this control as the custom data type of my variable. But is it recommended to do that?

Thank you

I don't have LV 8 but may still have a tip that's fresh in mind from a different post I just made.  If 2D dbl isn't available, you could use the "Reshape Array" function to turn it into a 1D array on one side and similarly reshape it back to 2D on the other side.  As long as the total # of elements specified by the 2D shape and the 1D shape are the same, no actual memory allocation is done and there should be very little overhead to the "reshaping".

Another way to do this is to specify your shared variable to be a custom control and create a control that simply has a 2-D array in it.  I've attached a zipped LabVIEW 8.2 project that shows both methods.  Enjoy!
