## 12.12. Numerical LibrariesTiger ships with an impressive array of resources used for numerical computing. In addition to support for 64-bit computing, including 64-bit pointers for passing large arrays, and the optimized and extended mathematical libraries, vecLib Subframework of the Accelerate framework. Includes BLAS, LAPACK, vDSP, vMathLib, vBasicOps, vBigNum, and vForce. It is located in */System/Library/Frameworks/vecLib.framework*(see*http://developer.apple.com/hardware/ve*).BLAS Complete and optimized set (levels 1, 2, and 3) of the basic linear algebra subprograms. (See http://www.netlib.org/blas/faq.html.) LAPACK Linear algebra package, written on top of the BLAS library. (See http://www.netlib.org/lapack/index.html.) Lapack is designed to run efficiently having most of the actual computations performed by optimized BLAS routines. vDSP Digital signal processing. (See http://developer.apple.com/hardware/ve/downloads/vDSP.sit.hqx.) vBasicOps A set of basic arithmetic operations. (See */System/Library/Frameworks/vecLib.framework/Versions/Current/Headers/vBasicOps.h*.)vBigNum A set of basic arithmetic operations on large (128-bit) integers. (See */System/Library/Frameworks/vecLib.framework/Versions/Current/Headers/vBigNum.h*.)vMathLib A set of basic vectorized transcendental functions, optimized for the Velocity engine. (See http://developer.apple.com/hardware/ve.) vForce A set of highly optimized elementary functions on many operands. (See */System/Library/Frameworks/vecLib.framework/Versions/Current/Headers/vForce.h*.)vImage Subframework of the Accelerate framework. A set of highly optimized image processing filters. (See */System/Library/Frameworks/vImage.framework/Versions/Current/Headers/vImage.h*.)
To compile code using a subframework of Accelerate you must include the header file with the following line of code. #include <Accelerate/Accelerate.h> For example, you can compile a program named $ |
