it is about power electronics for the student from university lecture notes thirth lesson...

说明：  用matlab绘制bezier曲线，逼近一个n形状。(Matlab draw with Bezier curve, approaching a n shape.)

主要是2维的forbild 头部体模的matlab代码(forbild 2d head phantom matlab codes)

本设计利用了数字信号处理的知识,基于MATLAB的GUI平台,实现了IIR与FIR各类滤波器的设计,能够绘制各种滤波器的幅频特性曲线,相频特性曲线,零极点图,冲激响应,阶跃响应等。(This design utilizes the knowledge of digital signal processing based on MATLAB GUI platform, the IIR and FIR filter design all kinds can draw a variety of filter frequency characteristic curve, phase-frequency characteristic curve, pole-zero figure, red shock response, step response and so on.)

说明：  模拟拓展卡尔曼滤波的计算，雅各比矩阵的运算(Extended Kalman Filter)
