《数字信号处理》一书讨论的内容，主要是离散时间信号的博氏变换和数字滤旋器，本书在该书内容的基础上，介绍了不再属于傅盟叶变换家族的另一种重要的变换一一希尔伯特变换。( Digital Signal Processing to discuss the contents of the book, mainly discrete-time signals and digital transformation Borrelia spin filter, and the contents of this book in the book, based on the introduction of the AU is no longer a Fourier transform Fu family, another important Hilbert transform 11.)

三维矢量有限元-矩量法电磁场分析程序。 EMAP5 is a full-wave electromagnetic field solver that combines the method of moments (MOM) with a vector finite element method (VFEM). It employs the finite element method (FEM) to analyze a dielectric volume, and employs the method of moments (MoM) to solve for currents on the surface of (or external to) this volume. The two methods are coupled through the fields on the dielectric surface.(Three-dimensional vector finite element- MoM electromagnetic field analysis program.

说明：  一般的最小二乘通常是一次拿到全部的数据， 对所有数据进行统一优化计算得到模型系数。递推最小二乘是以一种递推的方式计算最小二乘，每次使用最新的测量值，来不断更新模型系数。(General least squares usually get all the data at one time, and perform unified optimization calculations on all the data to get the model coefficients. Recursive least squares is to calculate the least squares in a recursive way, each time the latest measured value is used to continuously update the model coefficients.)
