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.

Comments : tsp_solve finds optimal solutions to geometric TSPs with 100 cities in about an hour (don't go to lenscrafters for this one.) It will soon have an asymmetric TSP optimal solution finder that will perform at approximately the same level.

f2c: Fortran to C

In case you had not already noticed it: a public domain, industrial strength, fortran-to-C translator named f2c exists. It has one great strength and one great weakness: "It is a true compiler". Thus the code generated always "works", at the price of frequently looking like fortran.

A lot of useful fortran libraries can readily be turned into working C using f2c, and the resulting C can often be made almost human after some hand-editing. The weakest link of f2c is code which involves matrices.

A pointer to f2c is at EOF. f2c is also inside Netlib, so you are probably better off figuring out how to use Netlib.


Other pointers

There is a lot of interesting C source in these fields which I know nothing about: The comp.dsp FAQ has some pointers to source code. Please send me complete entries to include in the above index.

A lot of 3rd party source code which hooks into the S statistical package uses computational engines written in C. With a little work you can extract useful source from this. Look in the S directory at Statlib/ for more pointers. If you find something which is remarkably useful and easy to extract, please tell me about it.

The same phenomenon operates to some extent for the XLispStat package. Look around on the umnstat.stat.umn.edu site.


Interesting sites

If you don't have ftp access, send email to ftpmail@decwrl.dec.com saying "help". You will get instructions on how to do ftp via email.

Juhana Kouhia (jk87377@cs.tut.fi) has setup a very nice service: Everything in this index (except for what is on {net,stat}lib) is mirrored in pub/sci/math/numcomp-free-c on nic.funet.fi Note: this site is in finland. If you are in the US, please try to find a site closer to you.

Books


Name        : C Mathematical Function Handbook
Author      : Louis Baker
Language    : C and C++
Version     : 757 pages, soft, including floppy, McGraw Hill, 1992, $50
Description : Code implementing the algorithms and formulas in
              Abramovitz and Stegun, with several chapters added.  It will 
              save you a lot of time as compared with writing code out of A&S.
              95% of the pages in the book are merely the source code, without
              even doing pretty printing.  It improves on A&S in (broadly)
              mathematical physics.

              The code does not show very good C competence.  The code
              and the book betray their development on a computer running
              MS-DOS.  Sometimes, more-recent algorithms which improve on A&S
              are ignored.
