  2. Syllabus • Beyond <math.h> • GNU Scientific Library

  3. Beyond <math.h> The C90 Standard Library contains only elementary math functions: 2

  4. C99 expands the number of built-in math functions: More macros and constants are defined. Complex numbers, operators, functions are supported. 3

  5. Even more comprehensive math abilities can be added to C by using commercial or free libraries. From Wikipedia article: List of numerical libraries GNU Scientific Library - popular, free numerical analysis library implemented in C. GNU Multi-Precision Library - for doing arbitrary precision arithmetic. IMSL Numerical Libraries - cross-platform libraries containing a comprehensive set of mathematical and statistical functions. LabWindows/CVI - libraries for analysis of measurement data, signal generation, windowing, filter functions, signal processing, linear algebra, array and complex operations, curve fitting and statistics. NAG - collection of numerical analysis routines which can be called from user applications running on a wide variety of hardware platforms. Alternative: Numerical Recipes (book with source code, also online version, not free) http://www.nr.com 4

  6. GNU Scientific Library Free to use: License = GPL Homepage: http://www.gnu.org/software/gsl 5
