Group Data

Function

This Step groups elements within a data list by index list. Multiple input ports can be set to perform grouping operations with the same index list within each data list at the same time. If the index list is [[0, 2], [1, 3, 4]] and the input data is [100, 20, 300, 40, 500], the output is [[100, 300], [20, 40, 500 ]].
