I've tried using MATLAB R2023b to generate bode plots and calculate DC gains of transfer function but I keep on receiving an error message: 'Wrong number of input arguments'

syms s
b = (s + 1)/(s + 100)
b =
(s + 1)/(s + 100)
>> k = dcgain(b)
Error using dcgain
Wrong number of input arguments.
>> bode(b)
Error using bode
Not enough input arguments.

Ran in:
Wrong syntax. Use the tf function, not syms for Control System Toolbox functions.
Try this instead —
s = tf('s');
b = (s + 1)/(s + 100)
b = s + 1 ------- s + 100 Continuous-time transfer function.
k = dcgain(b)
k = 0.0100
bode(b)
grid
.
