Hi, i want to plot the magnitude of displacement x(:,1) and i have this program but the curve displacement =f(rload) mentioned is false. Can someone help me please. functionxdot = equacte(t,x) % Function file for mass with spring. ...
How to plot Magnitude Response of the Savitzky Golay (SG) Filter using the FVTOOL?The nature of the graph should be like this (even zooming in on the above graph does not yield this result)
z = zfft(data(:,2)); The number of rows in the input signal must be a multiple of 48 (the decimation factor). Error in plot_fft_v8 (line 124) Also, I am thnking that probably pspectrum() can help because ThemeCopy pspectrum(xTable,'FrequencyResolution',10)Error usi...

plot(frequencyAxis,phase(Iv)); xlabel ('Hz'); ylabel ('Phase'); grid on; First, you need to plot the absolute value to get the magnitude. Second, the phase should reverse at the resonant frequency, and it does. (In a tuned circuit, the impedance goes from leading, or capac...
I changed your code to plot the full amplitude spectrum. This fixes the warning error, and the frequency plot extends up to 100 kHz. More later. 1 Comment William Rose on 12 Aug 2024 Edited: William Rose on 12 Aug 2024 Open in MATLAB Online Ran in: @ANAS HAMZAH, ...

Or, you can construct the response of the nonlinear model over a grid of frequencies by exciting the system with one sinusoid at a time. This is more easily done in Simulink if you import the identified model using the Nonlinear ARX block. Then, use F...
