The FFTW package was developed at MIT by Matteo Frigo and Steven G. Johnson. Here is a comprehensive alphabetical listing of the routines with links to GAMS for documentation and code examples. Version 3.0 includes more efficient online documentation and enhancements to linear algebra, optimization and linear equations. Routines and interfaces consistent over 65 supported computer platforms. IMSL C Numerical Libraries Version 3.0 - written in C for C programmers and based on the world's most widely called numerical subroutines.
New release includes new statistical functionality.
Operators and function modules that provide faster and more natural programming through an object-oriented approach. Native Fortran 90-coded, not translated, subroutines designed to fully optimize Fortran 90 features for efficient program execution. Programmers can leverage available CPUs, regardless of type, to maximize hardware investments and optimize Fortran application performance. Significant performance improvements to several Fortran 90 linear algebra algorithms. Optional use of MPI-enhanced functionality based on the computing environment.
