These codes require an ASCII input file called input.dat of the following form: Lower Limit on x Upper Limit on x Final Time Pressure for x<0 when t=0 Density for x<0 when t=0 Speed for x<0 when t=0 Pressure for x>0 when t=0 Density for x>0 when t=0 Speed for x>0 when t=0 These codes produce 8 ASCII OUTPUT files: density.out. Density vs. x entropy.out. Entropy vs. x mach.out. Mach number vs. x massflux.out. Mass flux vs. x pressure.out. Pressure vs. x sound.out. Speed-of-sound vs. x velocity.out. Velocity vs. x waves.out. A description of the solution in terms of the three waves defined in the book (+,-,0).

Boost C++ Libraries Free peer-reviewed portable C++ source libraries Boost C++ Libraries 基本上是一個免費的 C++ 的跨平台函式庫集合，基本上應該可以把它視為 C++ STL 的功能再延伸；他最大的特色在於他是一個經過「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++ 標準委員會的人開發的，同時部分函式庫的功能也已經成為 C++ TR1 (Technical Report 1，參考維基百科)、TR2、或是 C++ 0x 的標準了。 它的官方網站是：http://www.boost.org/，包含了 104 個不同的 library；由於他提供的函式庫非常地多，的內容也非常地多元，根據官方的分類，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 數學與數字（Math and numerics） 正確性與測試（Correctness and testing） 資料結構（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 Broken compiler workarounds 其中每一個分類，又都包含了一個或多個函式庫，可以說是功能相當豐富。

Computes all eigenvalues and eigenvectors of a real symmetric matrix a, ! which is of size n by n, stored in a physical np by np array. ! On OUTPUT, elements of a above the diagonal are destroyed. ! d returns the eigenvalues of a in its first n elements. ! v is a matrix with the same logical and physical dimensions as a, ! whose columns contain, on OUTPUT, the normalized eigenvectors of a. ! nrot returns the number of Jacobi rotations that were required. ! Please notice that the eigenvalues are not ordered on OUTPUT. ! If the sorting is desired, the addintioal routine "eigsrt" ! can be invoked to reorder the OUTPUT of jacobi.

The AP2406 is a 1.5Mhz constant frequency, slope compensated current mode PWM step-down converter. The device integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. It is ideal for powering portable equipment that runs from a single cell lithium-Ion (Li+) battery. The AP2406 can supply 600mA of load current from a 2.5V to 5.5V input voltage. The OUTPUT voltage can be regulated as low as 0.6V. The AP2406 can also run at 100% duty cycle for low dropout operation, extending battery life in portable system. Idle mode operation at light loads provides very low OUTPUT ripple voltage for noise sensitive applications. The AP2406 is offered in a low profile (1mm) 5-pin, thin SOT package, and is available in an adjustable version and fixed OUTPUT voltage of 1.2V, 1.5V and 1.8V
