Error/Mismatch in determing impedance using fft in simulink imported data.
Hello Everyone
I need to calculate the impedance of a more or less complex circuit using FFT. I have implemented the circuit in simulink and saved the voltage and current in the workapace using To Workspace block. However, after performing fft , I didnt quite get the expected result. Now to check if my code was right, I was testing it on a simple circuit. I have implemented a simple RC circuit . The model is attached. To determine impedance I am using the theory Z(w)=fft(voltage)/fft(current). R=Real (Z(w), X=Imag(Z(w)).
Now, The snapshot of the circuit–
The code I am using-
clc
% clear
Time = out.tout;
Load_Voltage = out.V_L;
Load_Current = out.I_L;
Fs = 1 / mean(diff(Time));
N = length(Load_Voltage);
fft_Load_Voltage = fft(Load_Voltage);
fft_Load_Current = fft(Load_Current);
fft_Load_Voltage_single_sided = fft_Load_Voltage(1:N/2+1);
fft_Load_Current_single_sided = fft_Load_Current(1:N/2+1);
frequencies = Fs * (0:(N/2)) / N;
frequency_of_interest =13.56e6;
[~, index] = min(abs(frequencies – frequency_of_interest));
Z1 = fft_Load_Voltage_single_sided(index) / fft_Load_Current_single_sided(index);
R1 = real(Z1);
X1 = imag(Z1);
fprintf(‘R: %.2f ohms, X: %.2f ohmsn’, R1, X1);
I have set the value of the resistor as 30 and the value of capacitor such as it would exibit -50 ohm at 13.56 Mhz, which is the driving frequency. But the results are off. The result I get is: R: 25.79 ohms, X: -37.52 ohms.
What is the problem here? Is it the code or anything with the simulink model. However if its just a resistive circuit the code gives correct result. This a very important step in a much bigger project. It is cricial.
Your help will be really appreciated.

How do we determine length and width of Pack object in Battery Builder?
Hi all,
I was working on Battery Builder from Simscape and could not find any function to return the width and length of the whole battery pack. I can try to export them to fig, but it is not accurate.

How can I rotate a volshow image programatically?
Hi!
I have a volshow image of a brain and I want to rotate it programatically (and then use getframe to write a video with writeVideo).
I tried using CameraPosition and CameraDirection of the Viewer3D parent object, but I have no clue how these work (and whether I need to move LightPosition with the camera). It seems highly complicated to move the camera around the brain like this. Is there an easier way to do that? Can I rotate the volume instead of the camera?Hi!

Time difference in year between table datetime values and now
I have a vector of datetime values. I would like to get a vector of years elapsed between the datetime values and the present. How do I do this?

Input data must be a real, numeric array, or a duration array. Use YEAR to extract year numbers from a

MATLAB locks up when I close a figure
I’m running R2022a on Mac OS V11.4. This symptom is very repeatable. It goes like this.
I start Matlab
I plot something
I close the figure with the Close button (the X)
I get the spinning wheel and Matlab is no longer responsive, has to be shut down. The spinning wheel never stops, I never am able to type in the command window again after that.
I just did the experiment with closing the figure with delete(). That worked fine. Then I tried again with the close button, and the wheel is spinning again.

Trying to test out opencv example from matlab and get error opencv2/opencv.hpp not found
I followed the directions from the Matlab video (https://www.mathworks.com/matlabcentral/fileexchange/47953-computer-vision-toolbox-interface-for-opencv-in-matlab).
I downloaded the apps Computer Vision Toolbox, Image Processing Toolbox, and Computer Vision Toolbox Interface for OpenCV in Matlab.
When I run this code: mexOpenCV matchTemplateOCV.cpp
I get the error: ‘opencv2/opencv.hpp’ file not found
I didn’t change anything and I’m following their instructions from the README.txt file.

Which is the difference between ‘multi-gpu’ and ‘parallel-gpu’ in ‘trainingOption’ function of the DeepLearning Toolbox?
Hi everyone,
I have two NVIDIA RTX 3060 installed on my local computer and I want to train a neural network in parallel on both GPUs. I am worried about which is the best strategy between ‘multi-gpu’ and ‘parallel-gpu’. Does anyone know how they work and which is the difference between ‘multi-gpu’ and ‘parallel-gpu’?

Use Multibody Spool component with only pulling force (can’t push)
I have a Simscape Multibody model that uses a hydraulic winch to control the extension and retraction of a level arm. When extending, I want the hydraulic winch system to control the overrunning load (motor operates as a pump that generates hydraulic pressure). However, I am seeing instead that the model is pushing the level arm.
Is there a way that the spool component can only behave like a rope and only apply pull forces? Or should I be going about this modeling in a different way?I have a Simscape Multibody model that uses a hydraulic winch to control the extension and retraction of a level arm.
