EEG_filter
- 自己编写的脑电滤波程序，实现0.3到120HZ范围的滤波-I have written EEG filtering process, to achieve the filtering range of 0.3 to 120HZ
electromagneticwaveTE13
- 利用matlab仿真金属圆柱体内电磁波分布，有助于掌握电磁波的传播情况。 把程序文档放入matlab的默认读取文档中，打开Cwave.m。Cwave.m是演示程序，由它调用其它函数。其中Z表示Kz*z，范围为0~2*pi。默认取2*pi为一个周期，num表示在一个周期内平均取多少个Kz*z值，默认为50(计算后每个值如Er都有五十幅图)。CWaveGuideCaculate函数用于计算Er,Efia,Hr,Hfia,Hz等值。CWaveGuideShow用于三维显示计算后得到的值，可以比较生
