Bode magnitude diagram of frequency response. If no output arguments are given, the response is printed on the screen.
Inputs
LTI system. Must be a single-input and single-output (SISO) system.
Optional vector of frequency values. If w is not specified,
it is calculated by the zeros and poles of the system.
Alternatively, the cell {wmin, wmax}
specifies a frequency range,
where wmin and wmax denote minimum and maximum frequencies
in rad/s.
Line style and color, e.g. ’r’ for a solid red line or ’-.k’ for a dash-dotted
black line. See help plot
for details.
Outputs
Vector of magnitude. Has length of frequency vector w.
Vector of frequency values used.

The following code
s = tf('s'); g = 1/(2*s^2+3*s+4); bodemag(g);
Produces the following figure
