求解O-S方程特征值，可以适用于多种条件下的O-S方程特征值计算(To solving OS Equation characteristic value, can be applied to a variety of conditions OS equation eigenvalue calculation)

用牛顿迭代法估计正弦信号的幅度，相位，频率，选用多次montecalor算法估计参数均值，并与理论上参数估计的CRLB下限进行比较。(Newton iterative method estimates the sinusoidal signal amplitude, phase, frequency, use multiple montecalor algorithm to estimate the parameters mean, and with the theoretical limit of parameter estimation CRLB compare.)

一个采用FLUENT计算气体-液体两相流的算例，附件文件可以直接用FLUENT打开，并附带了计算结果截图。(FLUENT is calculated using a gas- liquid two-phase study, attachment files can be opened directly by FLUENT, and the calculation results with the screenshot.)

说明：  LM莱文博格马夸特优化算法，python语言(this is a file of LM algorithm which was wroten by python language)

多相流cfd程序，用fortran实现，有多流体和dem计算功能，当然还有其它更多功能(MFiX is a general-purpose computer code developed at the National Energy Technology Laboratory (NETL) for describing the hydrodynamics, heat transfer and chemical reactions in fluid-solids systems. It has been used for describing bubbling and circulating fluidized beds and spouted beds. MFiX calculations give transient data on the three-dimensional distribution of pressure, velocity, temperature, and species mass fractions. MFiX code is based on a generally accepted set of multiphase flow equations. The code is used as a "test-stand" for testing and developing multiphase flow constitutive equations.)

复数矩阵的运算、包括乘、除、加、减、求逆等(Including all operations of the matrix)
