说明：  ARESLab是一个Matlab/Octave工具箱，用于使用多元自适应回归样条方法（也称为MARS）构建分段线性和分段三次回归模型。(ARESLab is a Matlab/Octave toolbox for building piecewise-linear and piecewise-cubic regression models using the Multivariate Adaptive Regression Splines method (also known as MARS).)

Robotics TOOLBOX The Toolbox provides many functions that are useful in robotics including such things as kinematics, dynamics, and trajectory generation. The Toolbox is useful for simulation as well as analyzing results from experiments with real robots. Have fun with the toolbox. It is self-explanatory and very (robotics) user friendly...see the robot.pdf
