PS Vector Norm block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
Simscape / Foundation Library / Physical Signals / Nonlinear Operators

Description

The PS Vector Norm block computes the Euclidean norm of a vector or matrix input physical signal:

$$y=sqrt\left(dot(u,u)\right)$$

where:

• y is the physical signal at the output port O.

• u is the physical signal at the input port I.

If the input signal is a matrix, then the block computes the column-wise vector norm.

Ports

Input

I — Input physical signal, untyped

physical signal

Input physical signal specified as a row or column vector or a matrix.

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.

Programmatic Use

Port: I

Output

O — Output physical signal, untyped

physical signal

Output physical signal. If the input signal is a vector, then the output signal is a scalar. If the input signal is a matrix, then the output signal is a vector or matrix representing the column-wise vector norm of the input matrix.

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.

Programmatic Use

Port: O

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"fl_lib/Physical Signals/Nonlinear Operators/PS Vector Norm"

Example: add_block("fl_lib/Physical Signals/Nonlinear Operators/PS Vector Norm","myModel/myBlock",MakeNameUnique="on")

For information about programmatic access to individual block parameters, see the Programmatic Use section of parameter descriptions on this page.
