有一学生成绩管理数据库如下表，要求建立一SAS数据集score，并输出显示 创建一个新的数据集class，新增平均成绩aver变量和等级考评grade变量，grade的值是根据aver值的大小给出A、B、C、D四个等级，并显示新数据集class(A student achievement management database as the table, called for the establishment of a SAS data set score, and output display create a new data set class, add an average score aver evaluation variables and grade level variables, grade values are based on the size of a aver value the A, B, C, D four grades, and displays the new data set of class)

说明：  利用Dijkstra算法来求网络图的最短路径，找到从起点P1到终点Pn的最短路径，由于上述算法使用了连接线中点的条件，不是整个规划空间的最优路径，然后利用遗传算法对找到的最短路径各个路径点Pi (i=1,2,…n)调整，让各路径点在相应障碍物端点连线上滑动(Use Dijkstra algorithm to find the shortest path network diagram to find the starting point P1 to the end of Pn from the shortest path algorithm is used as the midpoint of the condition of cable, not the entire optimal path planning of space, and then use genetic algorithm to find shortest path of each path points Pi (i = 1,2, ... n) adjusted to the path of obstacles in the corresponding endpoint connection point slide)

这是matlab的一本英文书，很适合初学者学习，是2007年出的，比较新(This is a matlab English books, is very suitable for beginners to learn, is out in 2007, a relatively new)

OFDM系统同步仿真的一个经典算法，避免SC算法产生的平台(OFDM system simulation of a classic synchronization algorithm, to avoid SC algorithms platform)

本程序的性能已经超过其他算法，hENcrDC参数可以得到很精确的幅值、频率、相位估计，给出接收信号眼图及系统仿真误码率，IMC-PID是利用内模控制原理来对PID参数进行计算，HsowisV条件线性调频脉冲压缩的Matlab程序,是国外的成品模型。( This program has exceeded the performance of other algorithms, hENcrDC parameter You can get a very accurate amplitude, frequency, phase estimation, The received signal is given eye and BER simulation systems, The IMC- PID is using the internal model control principle for PID parameters is calculated, HsowisV condition LFM pulse compression of the Matlab program, Foreign model is finished.)

语音滤波短时能量 短时过滤率 端点检测 都能得到相应的仿真波形(Speech s filtering the short time percolation of a short time energy a rate to carry to order examinations can get to homologously imitate true wave a form)

LTE系统中OFDM技术的仿真，包括循环前缀的插入去除，调制解调等主要步骤(The OFDM system of LTE, CP-OFDM, including of Cyclic Prefix modulation-demodulation and so on.)

Huffman code的matlab程序，用一幅图像作为training image得到像素的Huffman编码，然后编码另外一幅图像，求得average code length。(Huffman code of matlab program, with an image as a training image pixel Huffman coding, then coded another image obtained average code length.)

数字图像处理的一个作业，包含理想高通 巴特沃斯高通 高斯高通的频域增强的作业(A digital image processing operations, including the ideal high-pass Butterworth high-pass Gaussian high-pass frequency domain enhancement operation)

利用改进奇异值去除噪声，效果不错，带实例，可以参考(The improved singular value remove the noise, the effect is good, with examples, can reference)
