Notice that the index terminal symbol changes from a solid to an empty
box when you disable indexing. To restore a disabled index, use the
Enable Indexing command from the same menu.
You can extract subarrays along any combination of dimensions.
The following illustration shows how to extract a 1D row or column arrays
from a 2D array.
From a 3D array, you can extract a 2D array by disabling two index
terminals, or a 1D array by disabling a single index terminal. The following
figure shows several ways to slice a 3D array.
The following rules govern the use of the Index Array function to slice
arrays:
•
The dimension of the output object must equal the number of disabled
index terminals. For example:
–
Zero disabled = scalar element
–
One disabled = 1D component
–
Two disabled = 2D component
•
The values wired to enabled terminals must identify the output
elements.
