給定n個矩陣{A1,A2,…,An}，其中Ai與Ai+1是可乘的，i=1,2,…,n-1。考察這n個矩陣的連乘積A1A2…An。由于矩陣乘法滿足結合律，故計算矩陣的連乘積可以有許多不同的計算次序，這種計算次序可以用加括號的方式來確定。若一個矩陣連乘積的計算次序完全確定，則可以依此次序反復調用2個矩陣相乘的標準算法（有改進的方法，這里不考慮）計算出矩陣連乘積。若A是一個p×q矩陣，B是一個q×r矩陣，則計算其乘積C=AB的標準算法中，需要進行pqr次數乘。

For advanced geometry, most apps will prefer to load pre-authored meshes from a file. Fortunately, when using meshes, D3DX does most of the work for this, parsing a geometry file and creating vertx buffers for us. This tutorial shows how to use a D3DXMESH object, including loading it from a file and rendering it. One thing D3DX does not handle for us is the materials and textures for a mesh, so note that we have to handle those manually.

Whenever there is an application to write, breaking it up to small pieces is a great idea. The smallest piece of any application would probably be a data object, or a simple Bean in Java. Java Beans are simple Java classes that have a distinctive look and behavior. Their simplest purpose is to contain data and they accomplish this by having properties. Each property is actually a data-member containing/referencing the actual data and a couple of methods, a getter method and a setter method. Thus, the simplest data-bean describing a person could be expressed as such:

CAN1.c and CAN2.c are a simple example of configuring a CAN network to transmit and receive data on a CAN network, and how to move information to and from CAN RAM message objects. Each C8051F040-TB CAN node is configured to send a message when it s P3.7 button is depressed/released, with a 0x11 to indicate the button is pushed, and 0x00 when released. Each node also has a message object configured to receive messages. The C8051 tests the received data and will turn on/off the target board s LED. When one target is loaded with CAN2.c and the other is loaded with CAN1.c, one target board s push-button will control the other target board s LED, establishing a simple control link via the CAN bus and can be observed directly on the target boards.

此十字路口交通燈控制系統，分東西道和南北道，設東西道為A道，南北道為B道。規定：首先，東西路口紅燈亮，南北路口綠燈亮，同時開始25s倒計時，以7段數碼管顯示時間。25s倒計時結束后開始5s倒計時，南北路口的綠燈閃爍，計時到最后2s時，南北路口黃燈亮。完成1次這樣的循環需要30s。30s結束后，南北路口紅燈亮，東西路口綠燈亮，并重新30s倒計時，依次循環。若有緊急車輛要求通過時，此系統應能禁止普通車輛，而讓緊急車輛通過。

This document provides guidelines and describes how to easily port S60 2nd Edition C++ applications to S60 3rd Edition. The document has been written based on experiences of porting regular S60 2nd Edition applications, such as the S60 Platform: POP/IMAP Example [4] that can be downloaded from Forum Nokia. Code snippets from the example are shown in Chapter 8, “Application build changes,” and in Appendix A, “Code example." In addition, Appendix B, "Commonly used functions that require capabilities," and Appendix C, "Commonly used interfaces that have been changed or removed," provide useful information on some frequently used functions and interfaces in third-party applications.
