matlab

这个图论包里面包括好几个常用的程序 如最短路算法等(The graph on the package which includes several popular programs such as the shortest path algorithm)

该程序不使用matlab自带的程序，自主编写，进行简单更改可以实现多中功能，算法思想是滤波器的实现！(The program does not use matlab own procedures, self-writing, more than a simple change in function can be achieved, the algorithm idea is the realization of filters!)

说明：  用matlab绘制史密斯圆图，电子通信专业必备源码(Smith Chart in Matlab)

image watermarking method

分数阶仿真优化，可以解决许多分数阶问题。(Fractional simulation optimization can solve many fractional problems.)

说明：  　尺度不变特征转换(Scale-invariant feature transform 或 SIFT)(Scale Invariant Feature Transform (Scale-invariant feature transform, or SIFT))

现代信号处理中的功率谱估计的协方差算法。程序直观明了。(the algorithm in modern signal processing.)

主要用于石油地质行业，将地震采集的数据提取子波和计算反射系数(Mainly used in petroleum geology, the seismic acquisition of the data extracted the wavelet and calculation of reflection coefficient)

说明：  采用music算法进行谱峰搜索，并在不同信噪比、阵元数等情况下观察性能(MUSIC algorithm is used to search the spectrum peak)

直接转矩控制 同步电机的 传统控制pmsm 很好的仿真(Synchronous Motor Direct Torque Control the traditional control pmsm good simulation)
