There is also a small library for symbolically manipulating expressions. Name : Lapack++ Authors : J. Dongarra, R. Pozo, D. Walker Description : C++ version of some of lapack fortran code.

Contact pari-users-request@math.uic.edu or pari-implementors-request@math.uic.edu Description : PARI/GP is a package which is aimed at efficient computations in number theory, but also contains a large number of functions unrelated to number theory. It is somewhat related to a Computer Algebra System, but is not really one since it treats symbolic expressions as mathematical entities such as polynomials, series, matrices, etc..., and not as expressions per se. However it is often much faster than other CAS, and contains a huge number of specific functions not found elsewhere, essentially for use in number theory. In particular, and especially so in the present release, there is a very large package for working in general algebraic number fields. Systems : Binaries available for SPARC v7, v8, DEC Alpha, HP-PA. In the future, Mac (68k and powerPC). Intel hardware may have unsupported versions.

The program provides two methods to find the approximating segments, both satisfying an L infinity error norm and both SUB-OPTIMAL. The user specifies the tabulated function values and an error bound and the program returns the endpoints of the line segments that approximate the function. The operation is fast (essentially a single pass through the data) and works reasonably well on data with low noise. If the noise level is too high an alternative approach using smoothing splines should be used. Author : Original algorithms by Ivan Tomek and F.
