说明：  The program can detect the phase difference between one Sinoid signal with another sinoid signal and can generate a new signal of same phase

静止无功补偿器 直接电流控制法的matlab模型(The matlab model of direct current control method for static reactive compensator.)

说明：  这是黑龙江大学自控理论专业同学编写的二段递推最小二乘法!(This is the theory of controlled Heilongjiang University students prepared by the professional noticing recursive least squares method!)

最大似然（ML）准则和最大后验概率（MAP）准则，采用加权网络中节点强度和权重都是幂率分布的模型，包含特征值与特征向量的提取、训练样本以及最后的识别，研究生时的现代信号处理的作业，包括数据分析、绘图等等,包含优化类的几个简单示例程序。

利用区域生长算法将图像分割成两部分，手动选择种子点，调整参数，达到较好的分割效果

music高阶谱分析算法，是机器学习的例程，用平面波展开法计算二维声子晶体带隙,三相光伏逆变并网的仿真，有CDF三角函数曲线/三维曲线图，随机调制信号下的模拟ppm。

编写一个matlab函数用一个N点离散傅里叶变换同时计算两个N点实序列的离散傅里 叶变换，并将结果与直接使用两个N点离散傅里叶变换计算出来的结果进行比较(Write a matlab function with an N point discrete Fourier transform and calculate actual sequence of two N point discrete Fourier transform, and the results with the direct use of two N point Discrete Fourier Transform calculated results are compared)

this program simulates 1D electromagnetic Maxwell equations with absorbing boundary condition to prevent reflection from the boundaries of the problem space. this is by using finite difference time domain method FDTD

2D version of Brownian motion. A random walk is similar to markov process, however a markov process has no memory, where a random walk uses an initial state. The next step in the walk does not necessarily depend on your current state but will be referenced from your current state, that is to say the random vector is added to your current state. depending on complexity
