Array functions in LabVIEW access array data in row-major order. In a 2D array, row is the first, major index. Column is the last, minor index. In bigger multidimensional arrays, column remains the last index, and this function adds the more major indexes to the front. Thus, vol is the first index, followed by page, row, and column.

LabVIEW automatically provides an index input for each dimension of the array. element or subarray has the same type as the elements of n-dimension array. You can disable indexing along a dimension by leaving the corresponding index input unwired, unless you are indexing a 1D array.

Simply drag the mouse in the Index display to the left and increase the dimension. On the Block Diagram, the Array palette is available from the Functions palette in LabVIEW: Use these Array functions to create and manipulate arrays. Some of the most useful Array functions include:

In NI LabVIEW software, the array index is zero-based. This means that if a one-dimensional (1D) array contains n elements, the index range is from 0 to n – 1, where index 0 points to the first element in the array and index n – 1 points to the last element in the array. Clusters group data elements of mixed types.
