基于信道的历史信息来预测不同信道的未来可用时间可以帮助CR选择一个最佳信道进行信息传递。不同的预测准则应用到周期或是随机的开关模式中。一个CR可以学习以往不同信道的模式。我们提出一个简单的分类和学习方法去检测模式的类型和收集需要的信息用于智能信道的选择。MATLAB仿真结果显示提出的方案在随机信道的随机和周期模式中都有优越的表现。随着时间的变化，新到的切换次数减少到55 ，并且延迟时间也相应减少，而吞吐量却在提高。(Prediction of future availability times of different channels based on history information helps a cognitive radio (CR) to select the best channels for control and data transmission. Different prediction rules apply to periodic and stochastic ON-OFF patterns. A CR can learn the patterns in different channels over time. We propose a simple classification and learning method to detect the pattern type and to gather the needed information for intelligent channel selection. Matlab simulations show that the proposed method outperforms opportunistic random channel selection both with stochastic and periodic channel patterns. The amount of channel switches needed over time reduces up to 55 , which reduces also the delay and increases the throughput.)

这是个解代数方程组的matlab程序代码，发上来和大家共享(This is a solution of algebraic equations in matlab program code, the table and everyone shared)

有限差分法定温度分析程序：这个程序用有限差分法分析，当一个从一边受热的方型物体放置空气中，之后，其温度分布情况。(temperature analysis using finite difference method)

以二体问题为模型，从地球发射航天器探索火星，途中需经过一次无动力金星借力，寻找最优（总速度增量最小）的发射时间窗口和飞行时间，并绘制地球到金星的Pork-Chop发射能量等高线图。发射时间窗口为2023—2033年，总飞行时间不得大于2年。(Taking the two body problem as the model to explore Mars from the earth, it is necessary to seek an unpowered Venus transit force on the way to find the optimal time window and time of flight (the minimum total velocity increment), and draw the contour map of the Pork-Chop emission energy of the earth to Venus. The total launch time window is from 2023 to 2033, and the total flight time is not more than 2 years.)

用matlab实现的kmeans算法，是一个后台程序，没有调用其本身的kmeans算法，挺不错的(Using matlab to achieve kmeans algorithm, is a background process, not to call its own kmeans algorithm, very good)
