转载 instanceof作用---JAVA
instanceof是Java的一个二元操作符,和==,>, String s = "I AM an Object!"; boolean isObject = s instanceof Object; 我们声明了一个String对象引用,指向一个String对象,然后用instancof来测试它所指向的对象是否是Object类的一个实例,显然,这是真的,所以返回true,也就是i

Robotics Toolbox for Matlab Release 9
机器人学matlab用的工具箱,内有各种机器人学仿真计算工具函数,是学习机器人学必不可少的工具。同时还是《机器人学导论》中matlab作业题的工具。
This, the ninth release of the Toolbox, represents over fifteen years of development and a substantial level of maturity. This version captures a large number of changes and extensions generated over the last two years which support my new book “Robotics, Vision & Control”.
The Toolbox has always provided many functions that are useful for the study and simulation of classical arm-type robotics, for example such things as kinematics, dynamics, and trajectory generation. The Toolbox is based on a very general method of representing the kinematics and dynamics of serial-link manipulators.
These parameters are encapsulated in MATLAB ® objects - robot objects can be created by the user for any serial-link manipulator and a number of examples are provided for well know robots such as the Puma 560 and the Stanford arm amongst others. The Toolbox also provides functions for manipulating and converting between datatypes such as vectors, homogeneous transformations and unit-quaternions which are necessary to represent 3-dimensional position and orientation.
