SUMMARY
The discussion focuses on applying the Fast Fourier Transform (FFT) to a 1×N Green function in MATLAB, specifically addressing the challenge of non-periodicity. The user successfully utilized zero-padding by creating a zero matrix with the 'zeros' command and implemented a for loop to convert the Green function into a periodic function. This method effectively prepares the Green function for FFT analysis, ensuring accurate frequency domain representation.
