一阶弹性波方程交错网格差分法(时间2阶空间4阶，带边界条件) 最基础的波长快照(Elastic wave equation of first order staggered-grid difference method (time 2-order space of order 4 with boundary conditions) the wavelength of the most basic snapshot)

PID模糊小车直线控制，用MATLAB编写，运行后绘制小车运动轨迹(PID fuzzy car straight-line control, using MATLAB, and run after drawing the car trajectory)

简单的采样，设计一个输入序列，实现其采样，绘出采样后的时域波形(Simple sampling design an input sequence, to achieve its sample, drawn after the time-domain waveform sampling)

应用条件随机场知识对图像进行分割，场景理解。(Application CRFs knowledge of image segmentation, scene understanding.)

自己编的canny算子,可识别出图像中物体的轮廓,经典算法之一.(canny operator can identify the contours of objects in an image, one of the classic algorithms.)

1) 以身高为例，画出男女生身高的直方图并做对比； 2) 采用最大似然估计方法，求男女生身高以及体重分布的参数； 3) 采用贝叶斯估计方法，求男女生身高以及体重分布的参数（假定方差已知，作业请注明自己选定的一些参数情况）； 4) 采用最小错误率贝叶斯决策，画出类别判定的决策面。并判断某样本的身高体重分别为(160,45)时应该属于男生还是女生？为(178,70)时呢？(1) taking height as an example, draw the histogram of male and female students and compare them; 2) the maximum likelihood estimation method was used to calculate the height and weight distribution parameters of male and female students; 3) using Bayesian estimation method to find the parameters of height and weight distribution of male and female students (assuming the variance is known, please indicate some of the parameters selected by the job); 4) using the minimum error rate Bayes decision, draw the decision surface of category decision. And determine the height and weight of a sample respectively (160,45), should belong to the boys or girls? What about (178,70)?)

排序学习中经常用到的评价指标为MAP，本程序为该指标的计算函数。(calculate the mean average precision for learning to rank)

说明：  关于无线传感器的LEACH改进的协议，是基于改进粒子群算法的，很有帮助(LEACH for Wireless Sensor improved protocol is based on improved particle swarm algorithm, useful)
