# PRODUCT

Element-wise vector multiplication/division

### Description

That bloc computes element-wise multiplication or division of its vector inputs. The number of inputs and operation are specified with the Number of inputs or sign vector parameter.

• To multiply all the inputs between them, set this parameter to the number of inputs.

• To multiply/divide the input ui, set in this parameter a vector k with k[i] = +1 (multiply) or -1 (divide) for the input ui.

### Dialog box

• Number of inputs or sign vector

Set the number of inputs and the associated operation.

Properties : Type 'vec' of size N

• Error on divide by zero (1: yes) (0:no)

Halt the simulation on divide by zero.

Properties : Type 'vec' of size 1

### Default properties

• zero-crossing: no

• mode: no

• regular inputs:
