Sum
Purpose
Add and subtract input signals
Library
Control / Math
Description
The Sum block adds or subtracts input signals. In case of a single input, all elements of the input vector are summed or subtracted. Vectorized input signals of the same width are added or subtracted element wise and result in a vectorized output signal. If vectorized and scalar input signals are mixed, the scalar input signals are expanded to the width of the vectorized input signals.
Parameters
- Icon shape
- Specifies whether the block is drawn with a round or a rectangular shape. Round shape icons permit a maximum of three inputs.
- List of signs or number of inputs
- The inputs can be specified either with
a string containing + or - for each input and | for spacers, or
a positive integer declaring the number of summands.
