You can compute the modified Bessel functions of the first kind usingbesseli. Themodified Bessel functions of the second kind, denotedKν(z), form a second solution independent ofIν(z)given by Kν(z)=(π2)I−ν(z)−Iν(z)sin(νπ) . ...
以下是一个示例,展示了如何用MATLAB拟合第一类贝塞尔函数(也被称为"Modified Bessel function of the first kind"): ```matlab 定义目标函数 fun = @(x, y) besselI(x, y); 定义x和y的范围 x = linspace(-10, 10, 100); y = linspace(-10, 10, 100); 使用fminunc找到最优参数 options = optimop...
