GroupDelay

牛顿迭代，雅克比,求解非线性方程组 数值分析 MATLAB相结合(Jacobi NEWTON)

利用pid算法控制电机转速，转速可调，数码管显示，初学者实用(Using PID algorithm to control motor speed, adjustable speed, digital display, beginners practical)

该程序用fortran90编写，时域有限差分（FDTD)中的分裂场方法。解决了斜入射情况下周期结构的电磁散射问题。(FORTRAN90 prepared with the program, finite difference time domain (FDTD) method of splitting the market. Solved the case of oblique incidence of electromagnetic scattering from periodic structure issues.)

说明：  用四阶Runge-Kutta法解延迟微分方程组，用到的朋友看一下啊(Using fourth-order Runge-Kutta method for delay differential equations, a friend used to look at ah)

说明：  彭曼公式主要是计算蒸散发量，在水文和气象中有广泛的应用(Penman formula to calculate evapotranspiration primarily, widely used in hydrology and meteorology)

西安电子科技大学吴振森教授的波传播与电磁散射课件,里面有很多fortran计算的代码,此课程为博士课程,供专业人士学习.(The courseware of the Xidian University Professor Wu Zhensen wave propagation and electromagnetic scattering, which have many fortran code, this course is Dr. courses for professionals to learn.)

随机微分方程求解的一个很好的参考资料，算是比较基础的，深入浅出(Stochastic differential equations of a good reference, as a relatively basic, easy to understand)

完成了复数矩阵的计算,采用了并行算法原理，较快速的处理了稀疏矩阵方程结构。(Completed a complex matrix computation, parallel algorithm principle, more rapid processing of the sparse matrix equation structure.)

一些有用的fem用来matlab进行有限元分析编程的源代码(Some useful fem used to matlab for finite element analysis of programming source code)

这个是计算声传播的各种模型 包括简正波kraken波数积分scooter等模型 有很好的学习价值 (a system program for acoustic propagation calculation)
