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

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 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.

I think the following directory is missing from your path:
C:\Program Files\MATLAB\R2010a Student\toolbox\curvefit\splines
That is the directory where CSAPS appears in the full version of R2010b. I'm not sure if it just isn't included in the student version, or if it was somehow removed in your As noted in Jonas' answer, that folder isn't there in R2010a (it was still a part of the Spline toolbox).pathdef.m file.
