代数涡粘模型用于计算近壁湍流的速度场，1D 4阶RK 积分(Algebraic eddy viscosity model is used to calculate the near-wall turbulence velocity field, 1D 4-order RK integration)

说明：  对时间序列进行滤波，去掉噪声，得到平滑后的数据(Filters a time series via Lanczos method (cosine filter).)

储层产能预测文献，对于研究利用测井进行产能预测有帮助！(Prediction of Specific Productivity Index for Sihapas Formation in Uncored Wells of Minas Field Using Limited Available Core and Log Data)

本程序用于电力系统不对称故障计算，matlab实现，希望有所帮助(This procedure for the asymmetry of power system fault calculation, matlab realize the hope that help)

dea的ccr模型、超效率模型的m文件和实例(The CCR model of DEA, the M files and examples of the super efficiency model)

故障检测，分别是pls和pca，计算spe和t2控制量。(Fault detection is pls and PCA, respectively, to calculate SPE and T2 control.)

深入浅出蒙特卡洛方法，蒙特卡洛仿真高级学习文档资料，提供深入浅出的学习帮助(Simple terms Monte Carlo method, Monte Carlo simulation of advanced study and documentation, providing simple terms of learning to help)

说明：  计算两组向量之间的旋转矩阵。输入参数为在两个不同坐标系中的同名向量（模为1），返回参数是一个3X3的旋转矩阵。(The function of RM realize the rotation between two sets of vectors, whose magnitude are 1, defined in two different refrence frames. Input parameters are two sets of vectors r and b, return value is a rotaton matrix.)
