说明：  著名的seismiclab的代码 是地震学研究人员必备的工具(famous seismiclab code seismic study is an essential tool for officers)

这是一个用来对超声图像进行滤波的算法，是我按照论文自己编的，效果与论文中的一样。是stick filter。(This is the one used on the ultrasound image filtering algorithm is in accordance with papers their own series, the effect paper. Stick the filter.)

使用principal component analysis PCA减少特征数目(Use principal component analysis (PCA) to reduce the number features.)

fftshift 比较实数和复数傅里叶变换频谱的不同，以及N取值对其频谱特点的影响。(fftshift more real and complex Fourier transform spectrum of different, and the N values of the characteristics of its spectrum.)

用Matlab实现的倒立摆控制 (Using Matlab to achieve inverted pendulum control)

说明：  直接对反馈的转矩量来进行控制从而实现对直流无刷电机的控制，不需要在电机内部装传感器(The feedback torque is directly controlled to realize the control of the brushless DC motor without installing sensors in the motor)
