说明：  该程序实现的了2x2的mimo系统收发。运行system程序，可看到接受端的误码率曲线，星图。(the process of the realization of the 2x2 MIMO transceiver system. Operating system procedures, we can see the receiving end of BER curves, star maps.)

说明：  任意阵列输出数据的协方差进行奇异值分解，求出特征值和特征向量，利用信号子空间和噪声子空间的正交性，构造空间谱函数(Arbitrary array output data covariance singular value decomposition, eigenvalues and eigenvectors obtained using the signal subspace and noise subspace orthogonality spectral function space constructor)

Wigner-Ville 分布(简称 WVD)是典型的二次型变换，它定义为信号瞬时相关函数的傅立 叶变换。 由于在计算中不加窗操作，它避免了时域分辨率和频域分辨率之间的相互牵制。 已证明，对于单分量线性调频信号，WVD 的时频表示能量集中性最优。但也正因为不涉 及窗函数，在分析多分量信号时 WVD 会受到交叉项的干扰。(The Wigner-Ville distribution (WVD) is a typical quadratic transformation, which is defined as the Fourier of the instantaneous correlation function of a signal. Ye Bianhuan. Because of no window operation in the calculation, it avoids the mutual restraint between time domain resolution and frequency domain resolution. It has been proved that for the single component LFM signal, the WVD time frequency representation has the best energy concentration. But it is also because it does not involve. And window functions, when WVD is used to analyze multi-component signals, it will be interfered by cross terms.)

说明：  这是非线性整数规划模型求解分支定界迭代算法(This is a non-linear integer programming model to solve iterative algorithm branch and bound)

实现删除对象delete_object（可以连续删除多个对象），实现获取一个对象get_object（多个对象），get_types，get_schema，post_object，get_workflow，set_workflow,其中get_discussion有问题（python脚本就没有成功过）。(Delete_object deleted objects (you can delete multiple objects) in a row, realize the access to an object get_object (multiple objects), get_types, get_schema, post_object, get_workflow, set_workflow, there get_discussion problem (python scripts no) have been successful. )

最优化计算分析方面的程序入门资料小，适合初学者(Optimization calculation program started small data analysis, suitable for beginners)

此程序为MATLAB实现的配电网33节点潮流计算，方法为前推回代法。(MATLAB realization of this program for the distribution network 33 nodes in power flow calculation, and methods for the former to push back on behalf of the law.)

本人编写的ofdm系统中的em信道估计matlab仿真程序，可直接运行(I ofdm prepared by the system of channel estimation em Matlab simulation program can be run directly)

this is good codes from a typical book

计算方法中，拉格朗日插值法的源代码。在最后，绘出了拉格朗日插值法的图像和原图像的比较。原创。(Calculation method, Lagrange interpolation source code. In the end, draw a comparison image and the original image Lagrange interpolation. Original.)
