cxsc

C-XSC is the C language variant of the XSC (eXtensions for Scientific Computing) project. It provides routines that guarantee accuracy and reliability of results. Problem-solving routines with automatic result verification have been developed for many standard problems of numerical analysis, such as linear or nonlinear systems of equations, differential and integral equations, etc. as well as for a large number of applications in engineering and the natural sciences. Some of the features of C-XSC are: - Operator concept (user-defined operators) - Overloading concept - Module concept - Dynamic arrays - Controlled rounding - Predefined arithmetic data types real, extended real, complex, interval, complex interval, and corresponding vector and matrix types - Predefined arithmetic operators and elementary functions of the highest accuracy for the arithmetic data types - Data type dotprecision for the exact representation of dot products - Library of mathematical problem-solving routines with automatic result verification and high accuracy
