本程序可以实现在交错网格条件下的三维有限差分正演模拟(This procedure can be achieved under the conditions of the staggered grid finite difference forward modeling)

将ABAQUS的ODB结果文件按照人为要求在文本文档中记录(On ABAQUS ODB results file records in a text document in accordance with human requirements)

使用C编写的复数矩阵求逆，使用高斯消去法，已经和matlab结果做过对比，无误(Written in C and the complex matrix inverse, using the Gaussian elimination method, has been done and matlab results contrast, correct)

说明：  LM算法的c语言实现 拟合的函数为gauss函数(Levenberg-Marquardt Method)

LS_SVM 偏最小二乘结合支持向量机(The LS SVM partial least squares and Support Vector Machine)

开关电源电感计算案例，buck降压斩波输出电感的参数计算和选型(inductor parameter calculation of switching power supply)

内点法求解线性规划问题； 通过内点法实现了线性规划问题的求解； 内有说明文件；(Interior point method for solving linear programming problems through the realization of the interior point method for solving linear programming problem there is documentation )

说明：  集合卡尔曼滤波(EnKF) 数据同化方法可以避免了EKF 中协方差演变方程预报过程中出现的计算不准确和关于协方差矩阵的大量数据的存储问题,最主要的是可以有效的控制估计误差方差的增长,改善预报的效果。(Ensemble Kalman Filter (EnKF) data assimilation methods can be avoided in the EKF covariance forecasting the evolution equation arising in the course of the calculation is not accurate and on the covariance matrix of a large amount of data storage problems, the most important and effective control can be estimated error variance of the growth, improvement in forecasting results.)
