Matlab泰勒級數e^x變換爲1/e^x？

Question

我試圖通過修改，使E要進行以下工作代碼^ -x會的工作，基本上我試圖修改它，使E 1 -x爲1/E^x的 我真的不是知道怎麼做that..Here是我的代碼..

function [result] = eTaylor(x, n) 
% approximate e^x 
% using first n non-zero terms of the Taylor series 
% e^x = 1 + x + x^2/(2!) + x^3/(3!) + x^4/(4!) + ... 
% Input arguments: 
% x = real argument to function e^x 
% n = number of non-zero terms of Taylor series 
result = 0.0; term = 1.0; 
for i = 1:1:n 
result = result + term; 
term = term*x/i; 
end 

Answer 1

要獲得1/e^x你只需要計算e^(-x)。用-x代替x提供您的eTaylor功能，您就完成了！

oneOverExp = eTaylor(-x, n); 

PS，
這是最好not to use i as a variable name in Matlab。
