MATLAB 在 MATLAB 7.10.0 学生版中似乎找不到 csaps()

Question

我有一些使用 csaps() 的代码，Matlab 的 cubic smoothing spline fitting function我想将其提供给使用 MATLAB 7.10.0 (R2010a) 的学生。

由于某种原因，即使学生安装了曲线拟合工具箱，该功能似乎也不存在:

??? Undefined function or variable 'csaps'.

我在这里遗漏了什么吗？这是path的输出。

Answer 1

发布 2010b merged将样条线工具箱放入曲线拟合工具箱中。拥有 Spline Toolbox 许可证和有效服务契约(Contract)的用户在升级到 R2010b 时将获得 Curve Fitting Toolbox 许可证，以替换已停产的 Spline Toolbox。

csaps 是 R2010a 中 Spline Toolbox 的一个函数。因此，它在您的学生拥有的工具箱集中不可用。尝试看看您的学生是否可以将曲线拟合工具箱替换为样条工具箱，或者升级到 R2010b。
