Index array question

[LHX]

Hi everyone,

I know that I can use a reshape array to convert a 2D to 1D.

But I'm curious to knew how come when I wire a 2D array into an index array and there's no constant for the index inputs, the output comes out as a 1D array?

How does it work in this case? could someone please explain this to me?

Hi LHX,

IndexArray defaults to index the first row of a 2D-array as can be seen by it's non-filled 2nd index input:

Index Array functions always returns the element or subarray of n-dimension array at index. By default, if you do not wire any index input terminals, the first subarray indexes row 0, the second subarray indexes row 1, and so on.
