WebFeb 23, 2024 · DFT can be used for many things. One of them is to calculate an approximation of the ground state energy of a molecule. By calculating the ground state energies of all reactants, and all products, you can gain valuable information about a chemical reaction between them, such as an estimate of how much energy would be … WebThe Matlab function win_plot(win,fs) is listed in Appendix A. This function computes several window figures of merit, and plots the windowed N-point DFT of two sine waves located at f 0 = f s /8 (center of a bin) and f 1 = f s /4 + .5f s /N (edge of a bin), where N is the length of the window win. The inputs to the function are a window vector ...
