Description

The PS Product block outputs the element-wise product of two input physical signals:

$$O=I_1.*I_2$$

where

I1	Physical signal at the first input port
I2	Physical signal at the second input port
O	Physical signal at the output port

The signal unit at the output port is determined by unit propagation rules. For more information, see Physical Signal Unit Propagation.

Examples

Solenoid

A solenoid with a spring return. The solenoid is modeled as an inductance whose value L depends on the plunger position x. The back emf for a time-varying inductance is given by:

Ports

Input

I1 — Input physical signal, untyped

physical signal

First input physical signal to be added.

The port name is not visible in the block icon, but you can see this name in the underlying source file by clicking the Source code link in the Description tab of the block dialog box.

I2 — Input physical signal, untyped

physical signal

Second input physical signal to be added.

The port name is not visible in the block icon, but you can see this name in the underlying source file by clicking the Source code link in the Description tab of the block dialog box.

Output

O — Output physical signal, untyped

physical signal

Output physical signal.

The port name is not visible in the block icon, but you can see this name in the underlying source file by clicking the Source code link in the Description tab of the block dialog box.

Version History

Introduced in R2007a

R2019a: Unit Propagation

Prior to R2019a, this block did not propagate physical units.

If your model contains legacy blocks without unit propagation, use the Upgrade Advisor to upgrade your blocks to the latest version. For more information, see Upgrading Models with Legacy Physical Signal Blocks.
