The NAG fl90 (Fortran 90 Library), Release 4, provides over 254 user-callable procedures, giving easy access to complex and highly sophisticated algorithms, each designed and implemented using the performance, simplicity and flexibility of Fortran 90/95. These are equivalent to over 500 routines in the NAG Fortran 77 Library.

Targeted at programmers and software developers, scientists and engineers, the NAG fl90 has been designed from the outset to capitalize on the increased functionality, power and simplicity of Fortran 90.

New at Mark 4

The latest release of the NAG fl90 is enhanced with 43 new user-callable procedures in the areas of optimization, PDEs, sparse linear algebra, linear algebra, time series and approximation.

The new non linear sparse optimizer provides much more efficient algorithms then the dense optimizer where the profile to be optimized is based on sparse systems. This allows the solution of much larger problems in a given time frame.

As one would expect from NAG, the NAG fl90 is subjected to rigorous QA testing and only when it satisfies NAG's stringent accuracy standards is it released. As a result, Fortran 90/95 programmers can rely on the proven accuracy, robustness and reliability of these algorithms to give them the right answers, consistently. They will also find it's easy to integrate the NAG fl90 algorithms into existing Fortran 90/95 and Fortran 77 programs. The thread-safe functionality allows them to take advantage of developing multithreaded applications.

The NAG fl90 will be available first in Fujitsu VPP5000 UXP/V, IBM RISC System/6000 xlf90, Linux NAGf90, Linux Intel Lahey/Fujitsu lf95, Silicon Graph IRIX 6 SGlf90, Solaris (Sparc) Sunf90 and HP9000/700 HP f90 implementations.
