C Source Codes

I've written, converted, modified or simply admired a few C packages. Some of these are (hand converted) versions of routines I had written in FORTRAN. You may be able to use one of these libraries, or a routine or two from a library.

I don't mind receiving your comments, compliments, corrections or complaints, but please be warned that I will not do your damn homework.

For each package listed below, if you click on its name, you can see an expanded explanation of its purpose, a list of its contents, and copy the entire source code file, a sample calling program, or the results of running the calling program.

Currently available software includes:

• ANAGRAM, James Cherry's program to produce anagrams;
• BIO, binary data I/O, with byte swapping possible;
• BLENDC, 1/2/3D blending interpolation;
• CHRPAKC, a small set of character utilities;
• CR2LF, convert carriage return to linefeed;
• CRC, cyclic redundancy check;
• D2S, FORTRAN double<=>single precision converter;
• DIVDIFC, divided difference polynomials;
• GENETIC, simple genetic algorithms;
• GEOMETRYC, geometric calculations;
• GSL, GNU Scientific Library;
• HEXDUMP, hexadecimal dump of a file;
• HTMLINDEX, builds skeleton HTML pages from FORTRAN text;
• HULL, convex hull computation;
• INDEX, lists routines in a (marked up) FORTRAN text;
• IRISTOPC, SGI application that receives data through a socket, using the UDP protocol;
• JOINUP, joins a file that was split into chunks;
• MACHAR, dynamically computes constants that define the floating and double precision arithmetic;
• MPI, the message passing interface, used for parallel programming in distributed memory systems.
• OROURKE, computational geometry routines;
• PAGES, reports the number of pages in a file = (lines/60);
• PARANOIA, makes various checks of the properties of floating point arithmetic;
• PCTOIRIS, PC application, uses WINSOCK API to send data to another machine using UDP protocol;
• PROBC, probability distributions;
• RANLIB, random number generation;
• RBOX, generate random sets of points;
• SPLINE, interpolation and approximation with splines;
• SPLITUP, splits a file into chunks of given size;
• SPRNG, random number generators (RETIRED);
• SUBPAKC, a small utility library;
• TILER_C_3D, a 3D transfinite interpolation example;
• TOMS722, IEEE arithmetic support;
• TRIANGLE, Delaunay triangulation;
• UNCONTROL, remove control characters from a file;
• VORONOI, compute Voronoi diagrams and Delaunay triangulations of 2D data;
• WRAP, wrap long lines.
• XBIN, decodes a file that has been coded by BINHEX.
• XGL_WRAP, wrap long XGL text lines, breaking just after a tag closing (RETIRED).
