Pertransposition

For a continuous-time system with transfer function , the pertransposed system has the transfer function

The discrete-time counterpart is

Pertransposition of an LTI model sys is performed using

```
sys'
```

You can use pertransposition to obtain the Hermitian (conjugate) transpose of the frequency response of a given system. The frequency response of the pertranspose of , , is the Hermitian transpose of the frequency response of : .

To obtain the Hermitian transpose of the frequency response of a system sys over a frequency range specified by the vector w, type

```
freqresp(sys', w);
```
