On nonlinear simultaneous Chebyshev approximation problems ✩

This paper is concerned with the problem of nonlinear simultaneous Chebyshev approximation in a real continuous function space. Some results on existence are established, in addition to characterization conditions of Kolmogorov type and also of alternation type. Applications are given to approximation by rational functions, by exponential sums and by Chebyshev splines with free knots.  2003 El...

Parametric Fortran - A Program Generator for Customized Generic Fortran Extensions

We describe the design and implementation of a program generator that can produce extensions of Fortran that are specialized to support the programming of particular applications. Extensions are specified through parameter structures that can be referred to in Fortran programs to specify the dependency of program parts on these parameters. By providing parameter values, a parameterized Fortran ...
