What is the convention of Fourier transform in MATLAB?
Description.
Y = fft2( X ) returns the two-dimensional Fourier transform of a matrix X using a fast Fourier transform algorithm, which is equivalent to computing fft(fft(X).How to use FFT in MATLAB?
Double click on the scope of the signal for which you want to perform the FFT Analysis and go to Logging Tab, tick the “Log data to the workspace” option and select Save format as “Structure with Time” and click on Apply.
Run the simulation.
Double click Powergui >> Tools >> FFT Analysis.How to find FFT analysis in MATLAB?
Note The MATLAB convention is to use a negative j for the fft function.
This is an engineering convention; physics and pure mathematics typically use a positive j. fft , with a single input argument, x , computes the DFT of the input vector or matrix.
