我有一些使用csaps()Matlab 的三次平滑样条拟合函数的代码，我想给使用 MATLAB 7.10.0 (R2010a) 的学生。

由于某种原因，该功能似乎不存在，即使学生安装了曲线拟合工具箱：

我在这里错过了什么吗？这是 的输出path。

2010b 版将样条线工具箱合并到曲线拟合工具箱中。拥有 Spline Toolbox 许可证和有效服务合同的用户在升级到 R2010b 时将获得 Curve Fitting Toolbox 的许可证，以替换已停产的 Spline Toolbox。

csaps是 R2010a 中样条工具箱的功能。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换成样条工具箱，或者升级到 R2010b。

我认为您的路径中缺少以下目录：

C:\Program Files\MATLAB\R2010a Student\toolbox\curvefit\splines

也就是CSAPS 在R2010b完整版中出现的目录。我不确定它是否只是不包含在学生版本中，或者它是否以某种方式从您的pathdef.m文件中删除。 正如Jonas 的回答中所述，该文件夹在 R2010a 中不存在（它仍然是 Spline 工具箱的一部分）。
