Webb11 juni 2024 · The idea is to use Simpson's rule for the first m − 3 points and cover the remaining gridpoints with the Simpsons 3/8 rule. With the weight vectors defined above, we have w_simpson=ones (1,m-3); w_simpson (2:2:end-1) = 4; w_simpson (3:2:end-2) = 2; w_38 = [1 3 3 1]; I = sum (w_simpson.*f (1:m-3))*h/3 + sum (w_38.*f (m-3:m))*3*h/8 Webb我想作一個圖來說明一個簡單函數 y x 的Simpson 梯形積分公式。 scipy的simps和trapz函數有助於計算面積，但我也想在原始曲線上繪制梯形拋物線。我想知道是否有任何常規程序，如果沒有，了解如何制作這些圖的想法將很有幫助。
