根据错误提示，u和v的长度不匹配，v的长度为1xL，而u的长度为1x((t(i)-t(1))*1000)，特别地，当i=1时，u的长度为1x0。这种长度差异会导致程序报错。因此，我们可以在代码中调整u的定义，使用trapz(t(1:i),v(1:i))来替换掉原来的trapz函数。这样做是为了确保每个离散信号的值被累加起来...

In this video, you will learn how to compute frequency responses using MATLAB and Simulink. We will also delve into estimating frequency response models for Simulink models, focusing on those with components that challenge linearization, such as triggered subsystems, pulse width modulation, and state...
Pulse width modulation has many useful applications and so with this, a PWM signal simulation through MATLAB is presented that can be beneficial for analysis and model development. This paper aims to have a baseline how to present pulse width modulation graphically using MATLAB. The specific design...

Open in MATLAB Online Ran in: I am trying to cut frequencies above the cutoff frequency using the lowpass function, but it is not working. I am trying to cut the frequency by applying a lowpass filter to the tunnel current z multiplied by the reference ...
This is not valid for a DPC experiment, which leads to the third part of the model which is formed by the COMSOL-MATLAB interaction. The Re(CM) needs to be calculated for each time step to implement the impact of the frequency modulation into the COMSOL model and consequently produce p...
Matlab Deep Learning Toolbox was used for training and inference. It is possible to import the trained network to Python environment as well. Design validation, fabrication, and measurement Chips are fabricated using a 90-nm BiCMOS process. Relevant parts of the chip are shown in Figs. 6 and...
1.7a using the command fft in MATLAB and without considering the imaginary unit j; as a result, complex numbers are calculated. 3. The resulting data at positive frequencies are set to be zero. 4. The complex conjugates of the data at negative frequencies resulting from step 2 are ...
