As all of you know, MATLAB is a powerful engineering language. Because of some limitation, some tasks take very long time to proceed. Also MATLAB is an interpreter not a compiler. For this reason, executing a MATLAB program (m file) is time consuming. For solving this problem, Mathworks provides us C Math Library or in common language, MATLAB API. A developer can employ these APIs to solve engineering problems very fast and easy. This article is about how can use these APIs.

這是我自己寫的用于嵌入式設(shè)備的CGI程序，ANSI C編寫，嵌入式Linux中使用。這些CGI代碼是我在CGIC庫的基礎(chǔ)上加上了常用的一些外圍功能模塊函數(shù)，比如讀寫配置文件等。其中比較重要的是我自己實現(xiàn)的session控制、頁面模板方式（模板標(biāo)簽替換）和web多語言版本的一種我自己的實現(xiàn)方法。請參閱cgi_functions.c、session.c和multi-language.c。

A new cable fault location method based on wavelet reconstruction is proposed. In this method the difference between the currents of faulty phase and sound phase under the high voltage pulse excitation is used as the measured signal and is decomposed in multi-scale by wavelet transform, then reconstructed in single scale. Comparing with traditional fault location method by travelling wave, the presented method will not be interfered by the reflected wave from the branch joint of cables or from other positions where the impedances are not matched and not be influenced by fault types, otherwise, the reflected waves can be recognized even the faulty position is near to the measuring terminal, at the same time, the influence of the wave speed uncertainty can be reduced. The correctness of the proposed method is proved by simulation results.

基于OFDM的無線寬帶系統(tǒng)仿真It contains mainly two parts, i.e. link-level simulator and system-level simulator. Link-level simulator focus on a single-cell single-user scenario, where signal is transmitted from tx, and estimated at rx. Comparing the difference in tx/rx signal, the error rate can be found out. The output of the link-level simulator is the BLER/BER vs. SNR mapping table, that can be used for the system-level simulation. System-level simulator focus on a multi-cell multi-user scenario. For the sake of simplicity, it takes the mapping table aquired in the link-level simulation, measure the actural SNR, and finds the corresponding error rate.

定時中斷程序，源碼的注釋十分詳細，具體功能如下： 1.Frame 實現(xiàn)能有效降低VxWorks 內(nèi)存管理內(nèi)部/外部碎片的機制。 2. Frame 實現(xiàn)為系統(tǒng)提供軟定時器功能的機制，定時器timeout 信息以message 或其他快捷有效方式通知定時器申請者（Task）。 3. 參考實驗一要求，系統(tǒng)中每個Task 擁有自己的Message Queue，以此方式作為系統(tǒng)的消息驅(qū)動基礎(chǔ)。 4. 系統(tǒng)中各Task 應(yīng)使用同一類型框架，即統(tǒng)一的Task 框架。 5. 系統(tǒng)內(nèi)實體（Task/ISR）間傳遞的消息應(yīng)有統(tǒng)一格式（消息頭+消息體），可分短消息和長消息，但消息頭須至少包含消息ID。系統(tǒng)內(nèi)所有消息均有其唯一ID 標(biāo)識。

ExcpHook is an open source (see license.txt) Exception Monitor for Windows made by Gynvael Coldwind (of Team Vexillium). t uses a ring0 driver to hook KiExceptionDispatch procedure to detect the exceptions, and then shows information about the exception on stdout (using the ring3 part of the program ofc). The difference between this method, and the standard debug API method it that this method monitores all of XP processes, and the program does not have to attach to any other process to monitor it, hence it s harder to detect. The code currently is considered as ALPHA, and it has been reported to BSoD sometimes (on multi core/cpu machines). Take Care!
