![]() To change the font size of all text in a figure (titles, axis labels, legends, etc.) we need to search for all axes and text Here we demonstrate two possible changes that are commonly required. Fortunately, MATLAB allows you to change nearly every MATLAB is a wonderful tool for visualizing data and generating figures for papers and presentations however, the defaultĪppearance of these figures is not always sufficient for your needs. Fortunately MATLAB offers the function, squeeze, to fix just this problem:Ĭhanging Font Size and Line Width in Figures I = j =1, these singleton dimensions are an inconvenience for matrix operatione, etc. ![]() For the SISO systems we most often encounter, This is because the bode command accepts transfer function matrices in which case the (i,j,k) element of magnitude and phase corresponds to the jth input and ith output. You'll notice that though wout is a standard (n x 1) column vector, the magnitude and phase are actually (1 x 1 x n). The frequency vector by specifying only the range, win =. not in dB), phase is the phase in degrees, and wout is the output frequencies at which the response was evaulated, useful for instance if you let MATLAB automatically choose Where win is the input frequency vector in rad/s, mag is the magnitude in absolute units (i.e. Often it is neccesary to access this frequency response data directly, which is accomplished The Bode plot of a system,, shows the magnitude, (in dB), and phase (degrees) over a range of fregencies. Getting Magnitude and Phase Data for a System Please refer to the Matlab help page on bodeoptions for more details and optional parameters. Options.FreqUnits = 'Hz' % or 'rad/second', 'rpm', etc. To change between Hertz (Hz) and radians per second (rad/s) on the bode plot, use the following commands: s = tf( 's') Changing Font Size and Line Width in FiguresĬhanging the Frequency Units on the Bode Plots.Getting Magnitude and Phase Data for a System.Changing the Frequency Units on the Bode Plots.
