Block Diagram

7.

Place a Build Array function (Functions»Array) on the block 
diagram. Expand it with the Positioning tool to have five inputs.

8.

Pop up on the first input in the Build Array node and select Change to 
Array. Do the same for the fourth input. 

9.

Wire the arrays and scalars to the node. The output array is a 1D array 
composed of the elements of 

array 1

 followed by 

scalar 1

, 

scalar 2

, and the elements of 

array 2

 and 

scalar 3

, as the 

following illustration shows. 

 

10. Run the VI. You can see the values in 

scalar 1

, 

scalar 2

, 

scalar 3

, 

array 1

, and 

array 2

 appear in a single 1D array. 

11. Save the VI as 

Build Array.vi

 in the 

BridgeVIEW\Activity

 

directory. 

End of Activity 14-3.

Efficient Memory Usage: Minimizing Data Copies

To save memory, you can use single-precision arrays instead of 
double-precision arrays. For information about how memory is allocated, 
see the section Monitoring Memory Usage in Chapter 28, Performance 
Issues, in the G Programming Reference Manual.
