Engineering and Scientific Subroutine Library for AIX Version 3 Release 3: Guide and Reference

About This Book

The Engineering and Scientific Subroutine Library (ESSL) for AIX is a set of high-performance mathematical subroutines. ESSL is provided as two run-time libraries, running on IBM ^(TM) pSeries^(TM) and RS/6000^(R) POWER, PowerPC^(R), POWER2, POWER3, POWER3-II, and |POWER4 processors. ESSL can be used with Fortran, C, C++, and Programming Language/I (PL/I) programs operating under the AIX operating system.

This book is a guide and reference manual for using ESSL in doing application programming. It includes:

• An overview of ESSL and guidance information for designing, coding, and processing your program, as well as migrating existing programs, and diagnosing problems
• Reference information for coding each ESSL calling sequence

This book is written for a wide class of ESSL users: scientists, mathematicians, engineers, statisticians, computer scientists, and system programmers. It assumes a basic knowledge of mathematics in the areas of ESSL computation. It also assumes that users are familiar with Fortran, C, |and C++ programming.
