Description

The PS Abs block returns the absolute value of the input physical signal:

$$O=\left|I\right|$$

where

I	Physical signal at the input port
O	Physical signal at the output port

Untyped physical ports facilitate unit propagation. The output signal has the same physical unit as the input signal.

Ports

Input

I — Input physical signal, untyped

physical signal

Input 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.

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 R2008a

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.
