Designing a low pass IIR filter

说明：  EKF滤波 扩展kalman 滤波的matlab学习程序,特点是简单,能够设置输入参数,直观理解算法原理. (EKF extended kalman filter matlab filter learning process, is characterized by simple, to set the input parameters, intuitive understanding algorithm.)

矢量控制c代码中锁相环的求取，值得研究生学习借鉴和大功率边变频器相关技术人员借鉴。 (The vector control phase-locked loop of the strike in the c code, it is worth the graduate study reference and high-power side of the inverter and technical personnel draw.)

计算一个一位序列的极值（极大与极小） 并标注他们的位置 作图示意 并讨论在序列起始与终点的极值近似(Calculate a sequence of extremal (maximum and minimum) and marked their position plotted schematically and discussed in sequence starting with the end of the extreme value approximation)

说明：  通信原理中的数字调制方式与解调，包括了最常用的ask,psk,fsk的调制以及多种解调方式(the modulation and demodulation demo of ask, fsk ,dpsk and psk)

in this simulation we implement LTE schemes frequency reuse and we analysed interference co-chennel

说明：  MATLAB中的EKF、UKF工具箱，帮助更好地理解如何用将Kalman滤波器应用到截断数据模型中。(EKF and UKF Toolbox for matlab)

matlab常用函数参考手册，各类函数分类清晰明了，使用方便。(matlab reference manual for common functions, various types of function classification clarity, easy to use.)

说明：  MATLAB常用函数，包含常用的许多方面的功能，比较适用于初学者。(MATLAB FUNCTION)

用改进欧拉法求解常微分方程初值问题：用改进的欧拉法不仅提高了精度而且算法比较简单，(The improved Euler method to solve initial value problems of ordinary differential equations: Euler' s method with improved accuracy and the algorithm not only improve relatively simple,)
