学校电子设计竞赛时做的一个小DDS系统,功能较全,基于DSPBuilder,在MatLab R2009b中仿真通过(Electronic Design Competition when schools do a small DDS system function than the whole, based on DSPBuilder, in the simulation in MatLab R2009b by)

说明：  matlab中kron函数的C++实现，即对矩阵实现kron积，接口与matlab函数完全相同，可以作为替代程序使用(kron matlab functions in C++ implementation, the implementation of the matrix kron product, interface with matlab function exactly the same procedure can be used as an alternative)

短时傅里叶变换可以用差分模式来实现，对书上的运算式做了稍许的改变。改变-计算差分序列的第一列数据时用的是第一列的元素减去当前行的最后一列元素。原算法中采用的是第一列元素减去下一行第二列元素。原算法加窗之后结果比较好，不加窗时结果误差很大，而改变之后的算法不加窗效果依然很好。(Short time Fourier transform can be used to achieve the differential mode of expression on the book made a slight change. Change- calculating the difference sequence of the data with the first column is the first column of the matrix by subtracting the current element in the last column of row. Is used in the original algorithm subtracts the elements of the first column of the next row and the second column elements. After the results of the original algorithm windowed better, when the results window without great error, and after changing algorithms no window effect is still very good.)

copula时间序列模型在金融领域的应用(copula time series model applied in the financial sector)

解决线性规划优化问题，在lingo界面中得到广泛的运用(solve linear programming optimization problems, the lingo interface widely used)

时域有限差分法的2维代码~~~~很详细的，大家可以看看~~~~(Finite-difference time-domain 2 dimensions of the code )

非线性调频信号产生程序，根据给定的窗函数综合出相应的NLFM信号(Non-linear FM signal generation process, according to the given window function the corresponding NLFM signal integrated)

说明：  MUSIC方法是Schmidt 在 1979 年首先提出的,并于1986 年重新发表。该方法和 Roy 于1986 年提出的 Esprit方法都是早期经典的超分辨率 DOA 估计方法 即超瑞利限的方法 ,他们同属特征结构的子空间方法。(MUSIC method is Schmidt first proposed in 1979, and re-released in 1986. The method and Roy in 1986, Esprit proposed methods are early classic super-resolution DOA estimation method that is super-Rayleigh limit of the method, they belong to the same characteristic structure of the subspace method.)

说明：  simulink建模，pmsm的pi，smc控制(Simulink modeling and PMSM control of pi and smc)
