and I wish to Fourier transform the spatial part (of the data) to momentum space. However, FFT, FFT2 etc in matlab does not allow for variable (time or coordinate) inputs, one can only include the data, so there is no way to include the geometry of my system in the Fourier ...

The Fast Fourier Transform (FFT) is an efficient way to do the DFT, and there are many different algorithms to accomplish the FFT. Matlab uses the FFT to find the frequency components of a discrete signal. The following is an example of how to use the FFT to analyze an audio file in ...
Open in MATLAB Online Hey guys, I am tring to export the fft analysis result from fft tools in power gui to excel. I have 4 input signal available and 3 signal number (i.e. it is a 3 phase sytem with 4 different currents). I tried to export it to MATLAB c...
In MATLAB R2018b there is not a way to directly export the FFT analysis from the graphical interface opened from the Powergui block.The workaround is to use command line tools to obtain the desired data in the base workspace: 1. Get initial default stru...

how to create model in Simulink of MATLAB code? i was stuck in create FFT in Simulink and plotting frequency domain in Simulink.You can directly use a "MATLAB Function" block where you can encompass the FFT logic into a function and plot the dat...
how to do convolution without commandsThis is a little more complex than necessary - you don't need the first loop that reflects A, just change the index computation in the second loop to reflect the mathematical definition of convolution.You...
When I run your code, I do not get a plot like the one you show in the PDF. I get the follwoing two plots: I also get a warning error when I run your code: >> sampleFFT Warning: Integer operandsare required for colon operator when used as index. ...
