实现方面，通过MATLAB类设计可以轻松构造B-Spline曲线。MATLAB代码通常包括计算基函数、处理节点向量、实现控制点输入等功能。对于NURBS（Non-Uniform Rational B-Splines），它在B-Spline的基础上增加了权重，以更精确地表示曲线，尤其是圆锥曲线。NURBS的实现通常基于已有的B-Spline框架，仅需额外处理权重计算。

在MATLAB中，实现B样条类涉及几个步骤。首先，定义span_index函数来找到给定参数所处的区间，使用lower_bound和upper_bound函数定位节点向量中的序号。然后构造BSpline类，接受控制点、曲线阶次和参数范围。如果参数少于4，将默认设置umin和umax。中间非重节点均匀分布，而重节点通过设置来实现。对于非均匀...
