Bode 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 phase. 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); bode(g);
Produces the following figure
