Novel fast motion estimation algorithm based on optimizing predictive motion vector

CDMA系统仿真程序,很实用的仿真，希望大家好好利用(CDMA system simulation program)

说明：  使用matlab的simulink进行仿真GMSK，并画出仿真图。(GMSK is simulated with Simulink of matlab, and the simulation diagram is drawn.)

space time coding-alamouti scheme

说明：  自适应网格划分通用程序包，美国伯克利大学开发的共享软件包。(Adaptive Mesh generic package, the United States developed at the University of Berkeley's share package.)

学习Ruby特全的电子书。大多都是英文的，有一本是中文。(Many e-books for learning Ruby language.)

用于绘制加工稳定性耳垂图，可以确定不同参数下的稳定性加工极限(For drawing processing stability lobe diagram, can determine the limit of machining stability under different parameters)

共轭梯度法是介于最速下降法与牛顿法之间的一个方法，它仅需利用一阶导数信息，但克服了最速下降法收敛慢的缺点，又避免了牛顿法需要存储和计算Hesse矩阵并求逆的缺点，共轭梯度法不仅是解决大型线性方程组最有用的方法之一，也是解大型非线性最优化最有效的算法之一。(Conjugate gradient method is between the steepest descent method and Newton method between a method that only use the first derivative information, but the steepest descent method to overcome the disadvantage of slow convergence, but also avoids the need to store and calculate Newton Hesse matrix and the shortcomings of the inverse, conjugate gradient method is not only linear equations to solve large-scale one of the most useful, large-scale nonlinear optimization solution is also the most efficient algorithms.)
