Overview

Subtracts the last input from all other inputs

Discussion

The subtract module 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.
