三次hermite插值 matlab代码

以下是三次Hermite插值的Matlab代码：

function [y] = hermite(x, x0, x1, y0, y1, y0_, y1_)
% x: 插值点
% x0, x1: 插值区间
% y0, y1: 插值区间端点函数值
% y0_, y1_: 插值区间端点导数值

h = x1 - x0;
t = (x - x0) / h;
t2 = t * t;
t3 = t2 * t;

h00 = 2 * t3 - 3 * t2 + 1;
h10 = t3 - 2 * t2 + t;
h01 = -2 * t3 + 3 * t2;
h11 = t3 - t2;

y = h00 * y0 + h10 * h * y0_ + h01 * y1 + h11 * h * y1_;
end
