amplitude modulation

说明：  RRT 路径规划 基于二值图，压缩包内包含地图(RRT path planning is based on binary graph, and the compressed package contains map)

this is another gmm training matlab source code. it use k-means for initialization of parameter before trainig, not LBG algirhtm. so it is very helpful for GMM training

matlab时频分析工具包tftb，希望可以给需要的人，提供帮助(time-frequency analysis matlab toolkit tftb, hope to those who need to provide help)

Simulink model of a PV array

这个是对一个一维信号的Excel数据加载进matlab程序，然后进行巴特沃斯的低通滤波。(This is a one-dimensional signal of Excel data is loaded into the matlab program, and then Butterworth low-pass filtering.)

时频分析，用于时频分析，压缩文件，概率密度曲线 ，计算样本向量x的概率密度估计，返回在xi点的概率密度f，此时我们使用plot(xi,f)就可以绘制出概率密度曲线。(Time-frequency analysis, time-frequency analysis is used to compressed files)

Matlab最优化计算中的无约束一维极值问题(Matlab optimization calculations for unconstrained one-dimensional extremum problems)

利用全波法计算同轴线的特征模式以及同轴线内的场分布，对计算电磁学全波仿真的学习很有帮助(Use Full Wave Algorithm to calculate the eigenmodes and electromagnetic field distributions of coaxial line ,it will be very helpful for the learning of computational electromagnetics)

一种基于sift不变尺度的matlab实现，有程序实例以及使用方法(Based matlab sift the same scale to achieve program examples and use)
