SubtractInt32

Overview

Subtracts the last input from all other inputs

Discussion

Subtracts the last input from all other inputs. With an N-pin input, the output will be N-1 pins, and the Nth input will have been subtracted from all other inputs. The number of channels in the input channels needs to be identical in order for the module to properly work.
