qpsk通过信道信噪比估计，包括qpsk，8psk，16psk，16qam(qpsk through the channel SNR estimation)

说明：  matlab有关绘图命令介绍资料，希望给大家带来帮助。(Matlab orders about drawing introduced material, hope to bring you help.)

SSSC ON POWER SYSTEMS..VERY GOOD CODE AND WITH BASE PAPER .......FIND IT

四节点杆单元集成，及力，应力，刚度矩阵，使用MATLAB编制，此为m文件(QuadraticBarElement assemble force,stiff,stress)

说明：  运动目标跟踪的一种方法，可以简单的跟踪单个目标(Tracking a way to simply track a single target)

牛顿法， 快速解耦法， 。潮流计算在数学上属于多元非线性方程组的求 解问题，在用迭代法求解时涉及到大量的矢量和矩阵运算，因而寻求一个能高效 地处理矩阵运算的语言，将给潮流计算程序的编制带来巨大的方便.(fast flow electric Power flow calculation is mathematically the solution of multivariate nonlinear equations. Solving the problem involves a large number of vector and matrix operations when solving the iterative method, thus seeking a highly efficient solution. The language of matrix operation will bring great convenience to the compilation of power flow calculation program.)

超效率DEA剔除本身样本的MATLAB求解，只需更改输入输出，并能直接保存结果为Excel文件(Super Efficiency DEA reject MATLAB sample itself to solve, simply change the input and output, and can save the result as an Excel file directly)

说明：  商人过河的问题，三个商人各带一个仆人、、、(Merchants across the river mathematical modeling problem is a classic problem)

说明：  信道 估计中QAM的 代码 极具参考价值 很值得以看(Code channel estimation reference value is worth to see)
