對(duì)于非線性方程組F(X)=0，用fsolve函數(shù)求其數(shù)值解。fsolve函數(shù)的調(diào)用格式為： X=fsolve('fun',X0,option) 其中X為返回的解，fun是用于定義需求解的非線性方程組的函數(shù)文件名，X0是求根過(guò)程的初值，option為最優(yōu)化工具箱的選項(xiàng)設(shè)定。最優(yōu)化工具箱提供了20多個(gè)選項(xiàng)，用戶可以使用optimset命令將它們顯示出來(lái)。如果想改變其中某個(gè)選項(xiàng)，則可以調(diào)用optimset()函數(shù)來(lái)完成。例如，Display選項(xiàng)決定函數(shù)調(diào)用時(shí)中間結(jié)果的顯示方式，其中‘off’為不顯示，‘iter’表示每步都顯示，‘final’只顯示最終結(jié)果。optimset(‘Display’,‘off’)將設(shè)定Display選項(xiàng)為‘off’。

This book has grown out of my teaching and research at the University of Surrey and out of my previous experiences in companies such as Philips, Ascom and Motorola. It is primarily intended for use by students in master’s level and enhanced final-year under- graduate courses who are specialising in communication systems and wish to understand the principles and current practices of the wireless communication channel, including both antenna and propagation aspects

Nowadays sensors are part of everyday life in a wide variety of fields: scientific applications, medical instrumentation, industrial field, ...and, last but not least, popular mass production and low-cost goods, like smartphones and other mobile devices. Markets and business behind the field of sensors are quite impressive. A common trend for consumer applications is miniaturization which requires, on one side, a lot of research, development efforts, and resources but, on the other hand, allows costs and final application size reduction. In this scenario scientific community and industries are very active to drive innovation.

The first edition as well as its forerunner of Kuffel and Abdullah published in 1970 and their translations into Japanese and Chinese languages have enjoyed wide international acceptance as basic textbooks in teaching senior under- graduate and postgraduate courses in High-Voltage Engineering. Both texts have also been extensively used by practising engineers engaged in the design and operation of high-voltage equipment. Over the years the authors have received numerous comments from the text’s users with helpful suggestions for improvements. These have been incorporated in the present edition. Major revisions and expansion of several chapters have been made to update the continued progress and developments in high-voltage engineering over the past two decades.

It has been over a decade since the Chinese publication of Line Loss in Electric Power Systems. To keep pace with technological developments, I started a revision as early as 2002, following the main principles that the theoretical framework and characteristics of the first edition should be retained, with new contents added according to new problems after the reform of electric power systems and the new requirements for line loss management practices and in combination with practical experience.
