Well, bug reports would be better ;-)
The main function csape.m solves a linear system using full matrices at
the moment. That means you are limited to knot sequences of ~2000 points
(depends on your memory: n * n * 8 byte). I plan to use the sparse
package from Andy Adler in the near future.

Joerg Specht has provided some spline approximation functions. These can
be found at:
