matlab中常用电法各种装置的电磁正演计算(matlab often electricity law of electromagnetic devices forward calculation)

一次完成算法的最小二乘法的过程辨识代码。以m序列为输入量，用其lsim响应，作为辨识依据(One of the least squares algorithm to complete the process of identification code. To m for the input sequence with its lsim response, as a basis for identification)

matlab实现洛伦茨系统及相位图，已经测试无误可以直接运行(Lorenz system and matlab implementation phase diagram has been tested correctly can be run directly)

级联积分－梳状(Cascaded Integrator–Comb，CIC)滤波器，是种高 效滤波器。它是一种线形相位FIR滤波器，由工作在高抽样率的级联理 想积分器和低抽样率的级联微分器组成,根据抗混叠和抗镜像的指标 确定所需的级联数目。 (Cascaded integrator- comb (Cascaded Integrator-Comb, CIC) filter, is the kind of high efficiency filter. It is a linear phase FIR filter, high sampling rate by the work in the cascade of an ideal integrator and a low sampling rate of the cascade differentiator formed, according to anti-aliasing and anti-mirror of the indicators to determine the number of required cascade.)
