! Haha. I found some differences on the InternetAlgorithm, Found by different Daniel. There are probably the following types:1. Solving nses)2. Based on large-scale data sampling (Fast Fourier Transform (FFT ))3. parameter modeling (linear wave combination)4... Among them, the results obtained by the nses method are more realistic. After all, the results are based on the physical model, but the disadvantage is that the calculation is large, and the r
