Plot the phase as a function of frequency. Input array, specified as a scalar, vector, matrix, or multidimensional array. When the elements of z are non-negative real numbers, angle returns …

We show by treating a concrete example how you can use Matlab to plot the phase portrait of a linear system in the plane. The system of equations is written u’ = AA*u, where AA is a given …

A plot that shows representative sample of trajectories for a given first order differential equation is called phase portrait. This section shows how to include sample trajectories into tangent …

Replace abs you use for a magnitude plot with angle, like: plot(w,fftshift(angle(Xc))) ;title('Phase as a function of w');

Dec 3, 2024 · look at the following Matlab function, it can calculate phase spectrum as well as amplitude spectrum with a perfect accuracy:

Sep 28, 2015 · You can use the function freqz to plot the impulse response of this transfer function (both magnitude and phase). Here is the code I used: b = [2 0 3.125]; % numerator …

Dec 3, 2022 · Once we populate the matrices u and v, we use the MATLAB function quiver() to plot the phase portrait. This function is used to plot velocity vectors. In our case, the velocity …
