evalfr

---

Evaluate frequency response at given frequency.

---

Syntax

---

frsp = evalfr(sys, f)

Input argument

---

sys

LTI model

f

single frequency

Output argument

---

frsp

frequency response

Description

---

The function evalfr(sys, f) computes the value of the transfer function for a given system model represented by sys at the complex number f.

Example

---

numerator = {[2, 0], [1, 3]};
denominator = {[4, 0, 3, -1], [1 , 3, 5]};
sys = tf(numerator, denominator);
z = 1 + j;
