给定n个矩阵{A1,A2,…,An},其中Ai与Ai+1是可乘的,i=1,2,…,n-1。考察这n个矩阵的连乘积A1A2…An。由于矩阵乘法满足结合律,故计算矩阵的连乘积可以有许多不同的计算次序,这种计算次序可以用加括号的方式来确定。若一个矩阵连乘积的计算次序完全确定,则可以依此次序反复调用2个矩阵相乘的标准算法(有改进的方法,这里不考虑)计算出矩阵连乘积。若A是一个p×q矩阵,B是一个q×r矩阵,则计算其乘积C=AB的标准算法中,需要进行pqr次数乘。

After an introduction to the history of mobile communications, this guide considers the basics of mobile radio, the design of cellular and private radio systems, and issues of interworking with the fixed network. It then looks at the role of the mobile radio operator, the design and operation of mobile radio networks, the needs of large user groups, and relevant regulatory and government decisions. A final section focuses on career development through resolution of conflicts, understanding managerial issues, and professional vehicles.

The goal of our final project was to design an efficient elevator simulator that can accept input from a user and mechanically operate (on a small scale) a system of 4 floors and 3 elevators using pulleys and stepper motors. Users enter input using physical pushbuttons or the computer. This input is then processed by the MCU and orders are given to the elevators. We attempted to devise an algorithm that can optimally handle any number of floors. This project seemed like a fun challenge and something that had practical applications. Both of us have been frustrated at times by the inefficiency of some of the elevators here at Cornell, and we wanted to see if we could do a better job.
