I am trying to use the bode function on Matlab. The function i am trying to type in Matlab is H(s) = 10s/ (s+2).
This is my code
close all
clear all
s = tf('s')
H= 10*(s) /(s+2) ;
bode(H)
grid
x=1
The bottom is the error I keep getting.
Undefined function 'tf' for input arguments of type 'char'.
Error in Untitled (line 4)
s = tf('s')
How would i fix this?

The line
s = tf('s')
is correct in MATLAB's syntax. Which version of MATLAB are you using?

You may not have the Control System Toolbox, which is required for having tf().
Run "ver control" to find out
>> H=tf([10,0],[1,2])
H =
10 s
-----
s + 2
Continuous-time transfer function.

Well, you need purchase, download and then install from the Mathworks website.
