一个适合初学者学习和应用扩展的基于matlab的鼠标跟踪实例(mouse tracking)

自适应，arma ，gm ，都是根据论文写得，结果和论文一样，仅供参考。(Adaptive, arma, gm, are based on written papers, and papers as a result, are for reference only.)

二次规划为非线性规划的一种，若某非线性规划的目标函数为自变量x 的二次函数，约束条件又全是线性的，就称这种规划为二次规划。 (Quadratic programming as a nonlinear programming, if the objective function of a nonlinear programming quadratic function as independent variable x, and the constraints are all linear, call this plan for quadratic programming.)
