IsHermitian 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:
Simulink / Matrix Operations

Description

The IsHermitian block determines if the input is a Hermitian or a skew-Hermitian matrix.

Ports

Input

Port_1 — Input matrix

matrix

Input matrix, specified as a matrix.

Data Types: single | double | half | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | fixed point

Output

Port_1 — Hermitian or skew-Hermitian matrix

real scalar Boolean

A Hermitian or skew-Hermitian matrix, returned as a real scalar Boolean.

Data Types: Boolean

Parameters

Mode — Whether matrix is Hermitian or skew-Hermitian

Hermitian (default) | Skew-Hermitian

Identify the matrix as Hermitian or Skew-Hermitian.

Programmatic Use

Block Parameter: Mode

Type: character vector

Values: 'Hermitian' | 'Skew-Hermitian'

Default: 'Hermitian'

Block Characteristics

Data Types	Boolean | double | fixed point | half | integera | single
Direct Feedthrough	yes
Multidimensional Signals	no

a This block only supports signed integer types for the skew-symmetric mode.

Programmatic Use: Add Block

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

"simulink/Matrix Operations/IsHermitian"

Example: add_block("simulink/Matrix Operations/IsHermitian","myModel/myBlock",MakeNameUnique="on")
