THIS PACKAGE IS DEPRECATED

Please use the Julia implementation found in ApproxFun or the Matlab implementation in Chebfun. We leave the original Readme below.

Ultraspherical

Implements ultraspherical spectral methods for solving linear ODEs. This method results in matrices which are almost banded and a solver requires O(n) operations.

The package contains a C++, Matlab and Mathematica implementation. All implementations are experimental.

The Matlab implementation requires chebfun:

    http://www2.maths.ox.ac.uk/chebfun/

The Mathematica implementation requires RHPackage:

    http://www.maths.usyd.edu.au/u/olver/projects/RHPackage.html

The C++ implementation can be accessed from Mathematica (without RHPackage). See RunMathLink.nb.
