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

|What's New for ESSL Version 3 Release 3

• |The ESSL Libraries are tuned for the POWER4.
• |ESSL now supports the AIX 5L^(TM) for POWER Version 5.1, with |service, 32-bit and 64-bit kernels.
• |The ESSL header file now supports the C++ Standard Numerics Library |facilities for complex arithmetic and uses const qualifiers in the |function prototypes.
• |The Dense Linear Algebraic Equations Subroutines now include these new |LAPACK subroutines: |
  • |General Matrix Inverse
  • |Positive Definite |Real Symmetric or Complex Hermitian Matrix Factorization
  • |Positive Definite |Real Symmetric or Complex Hermitian Matrix Multiple Right-Hand Side Solve
  • |Positive Definite Real Symmetric Matrix Inverse
  • |Triangular Matrix Inverse |
• |The Linear Least Squares Subroutines now include this new |LAPACK subroutine: |
  • |Linear Least Squares Solution for a General Matrix |
• |Additional functionality has been added to the Packed Dense Linear |Algebraic Equation subroutines, _PPF. (See SPPF, DPPF, SPOF, DPOF, CPOF, ZPOF, SPOTRF, DPOTRF, CPOTRF, and ZPOTRF--Positive Definite Real Symmetric or Complex Hermitian Matrix Factorization.) |
