The toolbox solves a variety of approximate modeling problems for linear static models. The model can be parameterized in kernel, image, or input/output form and the approximation criterion, called misfit, is a weighted norm between the given data and data that is consistent with the model. There are three main classes of functions in the toolbox: transformation functions, misfit computation functions, and approximation functions. The approximation functions derive an approximate model from data, the misfit computation functions are used for validation and comparison of models, and the transformation functions are used for deriving one model representation from another.
KEYWORDS: Total least squares, generalized total least squares, software implementation.

Java Media APIs: Cross-Platform Imaging, Media, and Visualization presents integrated Java media solutions that demonstrate the best practices for using this diverse collection. According to Sun MicroSystems, "This set of APIs supports the integration of audio and video clips, animated presentations, 2D fonts, graphics, and images, as well as speech input/output and 3D models." By presenting each API in the context of its appropriate use within an integrated media application, the authors both illustrate the potential of the APIs and offer the architectural guidance necessary to build compelling programs.

Boost C++ Libraries
Free peer-reviewed portable C++ source libraries
Boost C++ Libraries 基本上是一個(gè)免費(fèi)的 C++ 的跨平臺函式庫集合，基本上應(yīng)該可以把它視為 C++ STL 的功能再延伸；他最大的特色在於他是一個(gè)經(jīng)過「同行評審」（peer review，可參考維基百科）、開放原始碼的函式庫，而且有許多 Boost 的函式庫是由 C++ 標(biāo)準(zhǔn)委員會的人開發(fā)的，同時(shí)部分函式庫的功能也已經(jīng)成為 C++ TR1 (Technical Report 1，參考維基百科)、TR2、或是 C++ 0x 的標(biāo)準(zhǔn)了。
它的官方網(wǎng)站是：http://www.boost.org/，包含了 104 個(gè)不同的 library；由於他提供的函式庫非常地多，的內(nèi)容也非常地多元，根據(jù)官方的分類，大致上可以分為下面這二十類：
字串和文字處理（String and text processing）
容器（Containers）
Iterators
演算法（Algorithms）
Function objects and higher-order programming
泛型（Generic Programming）
Template Metaprogramming
Preprocessor Metaprogramming
Concurrent Programming
數(shù)學(xué)與數(shù)字（Math and numerics）
正確性與測試（Correctness and testing）
資料結(jié)構(gòu)（Data structures）
影像處理（Image processing）
輸入、輸出（Input/Output）
Inter-language support
記憶體（Memory）
語法分析（Parsing）
程式介面（Programming Interfaces）
其他雜項(xiàng)
Broken compiler workarounds
其中每一個(gè)分類，又都包含了一個(gè)或多個(gè)函式庫，可以說是功能相當(dāng)豐富。

This effort started as an answer to the numerous questions the authors have
repeatedly had to answer about electrostatic discharge (ESD) protection and
input/output (1/0) designs. In the past no comprehensive book existed suffi-
ciently covering these areas, and these topics were rarely taught in engineering
schools. Thus first-time I/O and ESD protection designers have had consider-
able trouble getting started. This book is in part an answer to such needs.

高清電子書-C++ Primer Plus, 第6版英文版 1438頁Learning C++ is an adventure of discovery, particularly because the language accommodates several programming paradigms, including object-oriented programming,
generic programming, and the traditional procedural programming.The fifth edition of
this book described the language as set forth in the ISO C++ standards, informally
known as C++99 and C++03, or, sometimes as C++99/03. (The 2003 version was
largely a technical correction to the 1999 standard and didn’t add any new features.)
Since then, C++ continues to evolve.As this book is written, the international C++
Standards Committee has just approved a new version of the standard.This standard had
the informal name of C++0x while in development, and now it will be known as
C++11. Most contemporary compilers support C++99/03 quite well, and most of the
examples in this book comply with that standard. But many features of the new standard
already have appeared in some implementations, and this edition of C++ Primer Plus
explores these new features.
C++ Primer Plus discusses the basic C language and presents C++ features, making
this book self-contained. It presents C++ fundamentals and illustrates them with short,
to-the-point programs that are easy to copy and experiment with.You learn about
input/output (I/O), how to make programs perform repetitive tasks and make choices,
the many ways to handle data, and how to use functions.You learn about the many
features C++ has added to C, including the followi
