脉动风速功率谱估计,并与标准风谱进行对比(Power spectrum estimation of pulsating wind speed and comparison with standard wind spectrum)

此程序为潮流计算的最后一部分功率计算程序。(This program is the last part of the power flow calculation calculation program.)

对互谱法被动测距的原理及算法各个环节进行仿真验证：加权最小二乘估计中权系数的选取；相关窗长度的选取；各频段综合方法等等。最后实现了对9000m—15000m距离的测距(Cross-spectral method for passive ranging all aspects of theory and algorithms for simulation: weighted least squares estimation of the right of the selection coefficient related to the length of the selection window an integrated approach to the various bands and so on. Finally realize the right of ranging from 9000m-15000m)

这是最小二乘法多项式拟合的算法 很有参考价值的程序,(This is the least squares polynomial fitting algorithm is very useful procedure,)

利用Matlab计算quality factor. 输入是谐振波谱的数据，输出为：谐振频率，谐振幅度和quality factor。(Matlab coding. Calculate quality factor of resonator based on transmission spectrum data.)

分别采用Roe格式和AUSM格式求解一维黎曼问题，并将计算结果与解析解进行比较，发现这两种计算格式都能获得高的计算精度。(Roe scheme were used in this procedure and AUSM format to solve a 1-D RIEMANN problem, and numerical results were compared with the analytical solution, the results can be seen from these two formats have a solution with high accuracy.)

采用QR分解方法计算矩阵特征值和特征向量(computes a partial Schur decomposition of a square matrix or operator)

用C++来实现NEWTON迭代法解非线性方程算法数值分析，是数值分析里典型的一个算法。(In C++ to achieve NEWTON iterative numerical algorithm for solving nonlinear equations, numerical analysis is in a typical algorithm.)
