drawfunction

本程序用来计算matlab中两点坐标之间的距离，坐标必须是经纬度，并表明所要计算的单位(This procedure used to calculate the matlab in the distance between two coordinates, latitude and longitude coordinates must be, and show that to calculate the unit)

发声时的激励模型是一个以基因周期为周期的三角波，利用matlab绘制这个三角波的频谱。(When the voice of the incentive model is a genetic cycle cycle of triangle wave, use of matlab draw this triangle wave spectrum.)

用MATLAB实现LTP和LBP算法，并分别将处理后的图像显示出来(LTP and LBP algorithm by matlab, respectively, the processed image is displayed)

说明：  一个基于pca算法的简单的人脸识别系统，可以参考~(Pca-based algorithm for a simple face recognition system, can refer to ~)

求解最优化问题里的半定规划问题（SDP）经典并且十分有效的MATLAB程序包(a very efficient package for solving semi-definite programming)

matlab在有限元中的应用，平面常应变三节点单元，注解清晰，应用方便。(matlab in finite element applications, three-node constant strain plane unit, well commented, easy application. )

基于matlab的海洋通信的基础猜想，采用数字调制，2径仿真，其中损耗采用HUAWEI早年实测模型(Based on the basis of conjecture matlab marine communications, digital modulation, two-path simulation, in which the loss measured using early model HUAWEI)

说明：  假如数据中有N 个变量，而我们想抽取的样本的数量是M,那么在对数据进行抽样的时候，这种方法首先会把N个变量的设计空间均匀的划分开为M份，然后在每个划分好的区域中随机的抽取一点，最后，从这M个变量里，随机挑选之前选好的点，构成我们的样本(If there are n variables in the data, and the number of samples we want to extract is m, then when sampling the data, this method will first divide the design space of n variables into M parts evenly, and then randomly extract a point in each divided area. Finally, from the m variables, randomly select the previously selected points to form our sample)
