curve fitting - MATLAB can't seem to find csaps() in MATLAB 7.10.0 student edition -

i have code using csaps(), matlab's cubic smoothing spline fitting function want give student matlab 7.10.0 (r2010a).

for reason function doesn't seem exist, though student has curve fitting toolbox installed:

release 2010b merged spline toolbox curve fitting toolbox. users license spline toolbox , active service contract given license curve fitting toolbox replace discontinued spline toolbox when upgraded r2010b.

csaps function of spline toolbox in r2010a. thus, not available in set of toolboxes student has. try , see whether student can swap curve fitting toolbox spline toolbox, or upgrade r2010b.
