9.1.3 Using Optimized Libraries

In most situations, optimized commercial or shareware libraries perform standard computational procedures far more efficiently than you could by coding them by hand.

For example, the Sun Performance Library^TM is a suite of highly optimized mathematical subroutines based on the standard LAPACK, BLAS, FFTPACK, VFFTPACK, and LINPACK libraries. Performance improvement using these routines can be significant when compared with hand coding. See the Sun Performance Library User’s Guide for details.
