Array Subset (Clock-Driven Logic)
Returns a portion of an array starting at a specified index and containing a specified number of elements.
array
An n-dimensional array of any type.
index
First element, row, column, or page to include in the portion of array you want to return.
If index is less than 0, the node treats it as 0. If index is greater than or equal to the array size, the node returns an empty array.
Relationship between index Inputs and array Dimensions
For multidimensional arrays, index inputs correspond to row-major order. Thus, the first index corresponds last dimension of the array input, and the last index corresponds to the first dimension of the array input. The following table shows the relationship between four index inputs and the dimensions of a 4D array input.
| index Order | Corresponding Dimension in array Input | index Name |
|---|---|---|
| 1 | 4th | volume index |
| 2 | 3rd | page index |
| 3 | 2nd | row index |
| 4 | 1st | column index |
waveform
The waveform whose array of y values you want to use in this operation. This input becomes available when you wire a waveform to array.
length
subarray
The portion of array starting at index and containing length elements.
