The function generates a Bode magnitude pot of the (possibly MIMO) system
together with the location of the zeros and poles (which are indicated by circles and poles along the magnitude plots). The inputs are:
is the frequency vector
is the figure number of the plot
is the transfer matrix or state space realization of the system
is the style of the line to be plotted (e.g., sty=’b-‘)
is the legend info
In addition, it is possible to display a second Bode magnitude plot of another system as follows:
