Arrays and Clusters

The array structure consists of an index or element offset (highlighted left portion of the array structure) and the array elements (right portion of the structure). When the array structure is placed on the Front Panel window, the data type of the array is undefined as indicated by the grayed out portion of the array.

Figure 4.2 Index and Elements of an Array  

To define the array data type, drag and drop any data type, such as numeric, Boolean, string or cluster structure, onto the elements portion of the array structure.

Figure 4.3 Creating Arrays  

At this point, the newly defined array is anEmpty orNullArray because no elements of the array have been defined. This is indicated by the grayed out data type within theelements array structure.

Figure 4.4 Empty Arrays 

To define elements of an input array, select the element's index and enter the appropriate value. Figure 6.5 defines a numeric array with one element at index 0.

Figure 4.5 Defining Array Elements 

G arrays are zero-based. The last element index of an N element array is N1. Last Array Element and Undefined Nth Element are those of a 10 element array.

Figure 4.6 Last Array Element 

Figure 4.7 Undefined Nth Element 

An output array is created similarly to an input array with the exception that an output data type needs to be dropped into the array structure.
