This book is an introduction to two subjects:Matlaband numerical computing. This first chapter introducesMatlabby presenting several programs that inves- tigate elementary, but interesting, mathematical problems. If you already have some experience programming in another language, we hope that you can see how Matlabworks by simply studying these programs.

利用J-A模型求解磁滞回线时，使用龙格库塔四阶方法求解微分方程的代码，并可以将求解结果直接绘制成磁滞回线图像(When the J-A model is used to solve the hysteresis loop, the Runge-Kutta fourth-order method is used to solve the differential equation code, and the solution result can be directly drawn as the hysteresis loop image)

用matlab仿真的通信系统中的信道估计、统计、和判决(Estimated channel matlab simulation of communication systems, statistics, and judgment)

根据以下的平板光波导在波长为1550 nm时的折射率数据 1.作 出 不 同 波 导 芯 厚 度 d (0<d<15  m)对应的TE模式 与TM模式的色散图； 2.给出满足单模与双模传输的 波导厚度范围。 3.确定包层所需的最小厚度a 与b的值(The refractive index of the optical waveguide data at a wavelength of 1550 nm according to the following plate 1. do not make the same waveguide core thickness d (0 <d <15  m) corresponding to the TE mode And TM mode dispersion map 2. The single-mode and dual-mode transmission is given to meet the Waveguide thickness range. 3. To determine the required minimum thickness of a cladding And the value of b)

说明：  基于有限元理论的相关程序，都可以运行！同时包括多种数值计算方法，可供参考。(Relevant programs based on finite element theory can run!)
