问题描述

我有一些代码使用Matlab的三次平滑样条拟合函数csaps() 我想给使用MATLAB 7.10.0(R2010a)的学生.

I have some code using csaps(), Matlab's cubic smoothing spline fitting function that I want to give to a student with MATLAB 7.10.0 (R2010a).

由于某些原因，即使学生安装了曲线拟合工具箱"，该功能似乎也不存在:

For some reason the function doesn't seem to exist, even though the student has the Curve Fitting Toolbox installed:

我在这里错过了什么吗? 这是path的输出.

Am I missing something here? Here is the output of path.

推荐答案

发布2010b 将样条曲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.

Release 2010b merged the Spline toolbox into the Curve Fitting Toolbox. Users with a license for the Spline Toolbox and an active service contract were given a license for the Curve Fitting Toolbox to replace the discontinued Spline Toolbox when they upgraded to R2010b.

csaps是R2010a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"，或者升级到R2010b.

csaps was a function of the Spline Toolbox in R2010a. Thus, it is not available in the set of toolboxes your student has. Try and see whether your student can swap the Curve Fitting Toolbox for the Spline Toolbox, or upgrade to R2010b.

这篇关于MATLAB似乎在MATLAB 7.10.0学生版中找不到csaps()的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
