Here are some statements that generate a unit impulse, a unit step, a unit ramp, and a unit parabola. t = (-1:0.01:1)'; impulse = t==0; unitstep = t>=0; ramp = t.*unitstep; quad = t.^2.*unitstep; All of these sequences are column vectors that inherit ...The plot displays the magnitude (in dB) and phase (in degrees) of the system response as a function of frequency. bode automatically determines frequencies to plot based on system dynamics. If sys is a multi-input, multi-output (MIMO) model, then bode produces an array of Bode plots, each plot showing the frequency response of one I/O pair. If f is an equation or function of two variables, the default range for both variables is [–2π 2π] or over a subinterval of this range. ezplot (f,[min,max]) plots f over the specified range. If f is a univariate expression or function, then [min,max] specifies the range for that variable. This is the range along the abscissa (horizontal axis).For this example. plot the root-locus of the following SISO dynamic system: s y s ( s) = 2 s 2 + 5 s + 1 s 2 + 2 s + 3. sys = tf ( [2 5 1], [1 2 3]); rlocus (sys) The poles of the system are denoted by x, while the zeros are denoted by o on the root locus plot.

You can use the menu within the generated root locus plot to add grid lines, zoom in ...Rectangular Pulse Function. If a < x < b, then the rectangular pulse function equals 1. If x = a or x = b and a <> b, then the rectangular pulse function equals 1/2. Otherwise, it equals 0. The rectangular pulse function is also called the rectangle function, boxcar function, Pi function, or gate function. Anonymous functions require that you explicitly specify the input arguments as you would for a standard function, separating multiple inputs with commas. For example, this function accepts two inputs, x and y: myfunction = @ (x,y) (x^2 + y^2 + x*y); x = 1; y = 10; z = myfunction (x,y) z = 111. However, an anonymous function returns only one output.
