You can build arrays of numeric, Boolean, path, string, waveform, and cluster data types. The array index is zero-based, which means it is in the range 0 to n 1 , where n is the number of elements in the array. You must insert an object in the array shell before you use the array on the block diagram. Otherwise, the array terminal appears black with an empty bracket. To create an array control or indicator, select an array on the Controls>>Array & Cluster palette, place it on the front panel, and drag a control or indicator into the array shell. If you wire an array to a For Loop or While Loop input tunnel, you can read and process every element in that array by enabling auto-indexing. Use the Array functions located on the Functions>>All Functions>>Array palette to create and manipulate arrays. By default, LabVIEW enables auto-indexing in For Loops and disables auto-indexing in While Loops. Polymorphism is the ability of a function to adjust to input data of different data structures.
