MATLAB似乎在MATLAB 7.10.0学生版中找不到csaps（）

[poster]

我有一些使用csaps()代码，这是我想提供给使用MATLAB 7.10.0（R2010a）的学生的Matlab 三次平滑样条拟合函数 。

由于某些原因，即使学生已安装“曲线拟合工具箱”，该功能似乎也不存在：

Undefined function or variable 'csaps'. 我在这里想念什么吗？这是path的输出。

回答：

版本2010b将样条曲线工具箱合并到了曲线拟合工具箱中。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csaps中的样条工具箱的功能。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”替换为“样条曲线工具箱”，或升级到R2010b。
